A dynamic positioning system (DPS) uses thrusters and a control system to automatically maintain a vessel's position without anchors or mooring lines. It has three subsystems: a power system, thruster system, and DP control system. The DP control system coordinates with the other subsystems to maintain the vessel's position based on inputs like sea state. There are three types of DP systems that have increasing levels of reliability and redundancy in key components like power, thrusters, and controls.

DP Principles.pdf
Dynamic positioning systems work by using sensors to measure a vessel's position and heading in relation to environmental forces like wind, waves, and current. The dynamic positioning control system then uses an extended Kalman filter to estimate the vessel's position and motion as well as unmeasured environmental forces. It provides this data to a controller which calculates the necessary thruster forces to maintain the vessel's position and heading. Finally, a thruster allocation function distributes the required forces to each thruster and propeller in the most efficient way while also handling faults.

A High Order Sliding Mode Control with PID Sliding Surface: Simulation on a T...
Position and speed control of the torpedo present a real problem for the actuators because of the high level of the system non linearity and because of the external disturbances. The non linear systems control is based on several different approaches, among it the sliding mode control. The sliding mode control has proved its effectiveness through the different studies. The advantage that makes such an important approach is its robustness versus the disturbances and the model uncertainties. However, this approach implies a disadvantage which is the chattering phenomenon caused by the discontinuous part of this control and which can have a harmful effect on the actuators. This paper deals with the basic concepts, mathematics, and design aspects of a control for nonlinear systems that make the chattering effect lower. As solution to this problem we will adopt as a starting point the high order sliding mode approaches then the PID sliding surface. Simulation results show that this control strategy can attain excellent control performance with no chattering problem.
Autopilot Technology
Autopilot systems perform many of the same functions as human pilots by automatically controlling aircraft, vehicles or other moving objects. They use sensors and controllers to correct for errors and keep the craft on a desired path or attitude. A basic autopilot controls roll, pitch and yaw using effectors like elevators, rudders and ailerons. More advanced autopilots can perform complex maneuvers like landings. Key components include inertial sensors, controllers like Kalman filters and fuzzy logic, and electro-mechanical actuators. Autopilots are used widely in aircraft, vehicles, missiles, spacecraft and marinecraft to reduce workload and enable autonomous operations.
TVC main report
The document discusses thrust vector control systems which redirect engine thrust to control aircraft attitude. It focuses on the jet deflection method, where small airfoils located at the nozzle exit plane cause thrust to be vectored. The goals are to analyze this system using CFD. NACA 0012 airfoils are selected due to symmetrical shape and lift characteristics. CFD will be used to simulate fluid flow and predict system performance before manufacturing. Key benefits of CFD include insight into designs, ability to test variants efficiently, and compressing development cycles.

Development of a floating tow body for shallow water bottom and sub bottom im...
Abstract
A floating tow body which can be towed at a speed range of 2-6 knots with a pay load of 50 kg is designed and tested as part of the development of a Buried Object Location Sonar (BOLS) for shallow water imaging application. In this paper the results of extensive towing tank measurements of a floating tow body with the diamond and a cross shaped bow are presented and compared. A cross shaped bow with a stream lined body shape is adopted for the floating tow body for minimizing the drag as well as the turbulence during the tow. Both the bow shape as well as the dimensions of the body is optimized based on the towing tank experimental results so that the body can be towed smoothly with minimum turbulence to avoid acoustic noise generation during the SONAR tests. An iterative experimental procedure is carried out in finalizing the dimensions and the shape of the tow body.
Keywords: Floating tow body, bow shape, towing test.

This document describes the design, testing, and evaluation of a rudder actuation system for an autonomous vehicle. The system uses a microcontroller to control a DC motor that positions the rudder based on GPS data, replacing existing hydraulic actuators. It calculates the angle needed to correct deviations from the desired path using triangulation. Test results showed the system can calculate error angles accurately and drive the motor within 0.312 ms to correct course. While performance could be improved with advanced components, this design demonstrates a working rudder control system for autonomous guidance without human input.
Paper for robust control.pptx
1) The document discusses aircraft flight control in the case of an engine out (EO) scenario. When one engine fails, a yaw torque is created which can cause stability issues like large yaw rates and sideslip angles.
2) It proposes using a robust yaw-lateral decoupling control method to prevent energy from the failed engine transferring from yaw motion into roll motion. This would help reduce structural loads on the aircraft.
3) The controller works by defining a decoupling point where lateral acceleration is not affected by forces from the wings and fuselage. It then regulates the rudder to balance torques and make yaw rate non-observable from lateral acceleration at this point, achieving unilateral decoupling.

2. The main design objectives of any control system are: achieving the desired transient response, minimizing steady-state error, ensuring stability, and making the system robust to parameter variations.
3. The total system response C is found using superposition as C = CR + CU1 + CU2, where CR, CU1, and CU2 are the individual
Navigation of Mobile Inverted Pendulum via Wireless control using LQR Technique
Mobile Inverted Pendulum (MIP) is a non-linear robotic system. Basically it is a Self-balancing robot
working on the principle of Inverted pendulum, which is a two wheel vehicle, balances itself up in the vertical
position with reference to the ground. It has four configuration variables (Cart position, Cart Velocity,
Pendulum angle, Pendulum angular velocity) to be controlled using only two control inputs. Hence it is an
Under-actuated system. This paper focuses on control of translational acceleration and deceleration of the
MIP in a dynamically reasonable manner using LQR technique. The body angle and MIP displacement are
controlled to maintain reference states where the MIP is statically unstable but dynamically stable which
leads to a constant translational acceleration due to instability of the vehicle. In this proposal, the
implementation of self balancing robot with LQR control strategy and the implementation of navigation
control of the bot using a wireless module is done. The simulation results were compared between PID control
and LQR control strategies.

Cruise control simulation using matlab
Cruise control systems use feedback control to maintain a constant vehicle speed set by the driver. A cruise control system measures the current vehicle speed, compares it to the desired speed, and automatically adjusts the throttle according to a control law to account for external disturbances. Modeling the vehicle as a first order mass-damper system and applying Newton's second law derives the system transfer function. A proportional controller meets some performance criteria, but a lag controller is also needed to reduce the steady-state error to within acceptable limits.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
