Additionally, based on the security analysis conducted, the paper recommends the implementation of countermeasures and security approaches to address vulnerabilities and ensure the integrity and reliability of the system. By incorporating these measures, smart irrigation technology can revolutionize water management practices in agriculture, promoting sustainability, resource efficiency, and safeguarding against potential security threats.
Advanced control scheme of doubly fed induction generator for wind turbine us...
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.

PROJECT REPORT ONdfervrvvrtvrvrttvr.pptx
- 1. PROJECT REPORT ON : G e n e v a M e c h a n i s m Submitted by : Group(21) • Mohamed Fathy Mubarak • Mohamed Abdel- monem • Mohamed Mahrous Hanfy • Mohamed Nasr Ibrahim Guide by : • Dr.Wesam Farouk • Eng. Mohamed Elshamy 5/10/2024
- 2. INTRODUCTION • The Geneva drive is a gear mechanism that translates a continuous rotation into an intermittent rotary motion. The rotating drive wheel has a pin that reaches into a slot of the driven wheel advancing it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps.
- 8. Calculations Geneva gear auto calculating site this site is amazing! Through this site we can easily calculate Geneva gear parameters and check the motion(animation). http://benbrandt22.github.io/genevaGen/
- 13. CRITERIA FOR SELECTION OF MATERIAL: The material for different components was selected by assessing tensile strength and modulus, flexural strength and modulus, impact strength, compressive strength, fatigue endurance, creep, and stress-relaxation properties depending on the application. This ensures that design will work efficiently without any probability of failure. However, unexpected conditions like being subjected to a higher load than expected or being damaged by a chemical can affect the system. Furthermore, the cost factor is also very important in selecting material.
- 14. 1. Frame/Stand: Purpose: This is the part which bears the load of all other components as they are mounted on it. The frame material must have the capability to endure the load and offer minimum deformation Material: Steel 37
- 15. 2. Geneva Mechanism: It will consist of a Drive Wheel and a Driven wheel. Purpose: It will change continuous circular motion into fixed step circular motion. The rest of its mechanism has been explained earlier. Material: Steel 37
- 16. 3. 12V DC motor: Purpose: A DC motor is a device to convert electrical energy input to mechanical/kinetic energy output via a simple mechanism that uses magnetic field and electricity to produce a torque. The DC motor will be connected to the Geneva drive wheel, causing it to rotate due to the torque produced in it. We can control the rotation speed of the Geneva Drive wheel by varying the supplied Voltage. Greater the voltage, greater the speed of rotation
- 18. APPLICATIONS 1. Modern film projectors may also use an electronically controlled indexing mechanism or stepper motor, which allows for fast-forwarding the film. 2. Geneva wheels having the form of the driven wheel were also used in mechanical watches, but not in a drive, rather to limit the tension of the spring, such that it would operate only in the range where its elastic force is nearly linear.
- 20. ADVANTAGES Maintains good control of its load at all times. Low cost. Saves Man Power. Saves time. Easy setup in an industry. Does not require stepper motor.
- 21. DISADVANTAGES Very difficult to change timing once design is chosen. The Geneva is not a versatile mechanism. The ratio of dwell period to motion is also established. Once the no of dwells per revolution has been selected.
