A proportional–integral–derivative controller (PID controller) is a control loop feedback mechanism (controller) commonly used in industrial control systems. A PID controller continuously calculates an error value as the difference between a measured process variable and a desired setpoint.
The ability to tune a PID loop manually is an art that is quickly becoming scarce, but, like driving a car with a stick shift, it can be very helpful in the right circumstance. In industrial processes automation, most modern control loops are equipped with an auto-tuning algorithm, but in spite of this, there are some loops these automated methods cannot tame.
Having knowledge of the different tuning elements and how to adjust them can help you bring these unruly loops under control. If you have the responsibility to keep the processes running at your plant or factory, this webinar will help you better understand the basics of PID control.
In this webinar you will learn:
The purpose of each of the PID tuning elements
How adjusting the individual PID elements will affect the process
General PID profiles for pressure / flow loops
General PID profiles for temperature loops
An explanation of some supporting parameters like cycle time, manual reset, and anti-reset windup
Types of Controllers
Process control_ mechatronics engineering.
Control system is a combination of various elements connected as a unit to direct or regulate itself or any other system in order to provide a specific output is known as a Control system.
Components of a Control System
1.Controlled process: The part of the system which requires controlling is known as a controlled process.
2. Controller: The internal or external element of the system that controls the process is known as the controller.
3. Input: For every system to provide a specific result, some excitation signal must be provided. This signal is usually given through an external source. So, the externally provided signal for the desired operation is known as input.
TYPES OF DISTURBANCE:
1.an internal disturbance is generated within the system. 2.an external disturbance is generated outside the system and is an input.
Types of Control System:
1.Open loop control systems in this control system the
output is neither measured nor fed back for comparison
with the input.
2.Closed loop control systems in this control system the
actuating error signal, which is the difference between
the input signal and the feedback signal, is fed to the
controller so as to reduce the error and bring the output
of the system to a desired value.
PID
The PID control scheme is named after its three correcting terms, whose constitutes the manipulated variable (MV). The proportional, integral, and derivative terms are summed to calculate the output of the PID controller.

Design and Analysis of PID and Fuzzy-PID Controller for Voltage Control of DC...Francisco Gonzalez-Longatt
DC microgrids are desired to provide the electricity for the remote areas which are far from the main grid. The microgrid creates the open horizontal environment to interconnect the distributed generation especially photovoltaic (PV). The stochastic nature of the PV output power introduces the large fluctuations of the power and voltage in the microgrid and forced to introduce the controller for voltage stability. There are many control strategies to control the voltage of a DC microgrid in the literature. In this paper the proportional-integral-derivative (PID) and fuzzy logic PID (FL-PID) controller has been designed and compared in term of performance. Performance measures like maximum overshoot and settling time of FL-PID compared with the PID proved that the former is better controller. The controllers are designed and simulated in the MATLAB programming environment. The controllers has been tested for the real time data obtained from Pecan Street Project, University of Texas at Austin USA.
A simple, widely used control method. This presentation will provide an introduction to PID controllers, including demonstrations, and practise tuning a controller for a simple system.

Metal cutting tool position control using static output feedback and full sta...Mustefa Jibril
In this paper, a metal cutting machine position control have been designed and simulated using
Matlab/Simulink Toolbox successfully. The open loop response of the system analysis shows that the system needs
performance improvement. Static output feedback and full state feedback H 2 controllers have been used to increase
the performance of the system. Comparison of the metal cutting machine position using static output feedback and
full state feedback H 2 controllers have been done to track a set point position using step and sine wave input signals
and a promising results have been analyzed.

• On-Off Controller
• P Controller
• PI Controller
• PD Controller
• PID controller
3. On-Off Controller
• On-Off control is the simplest form of feedback
control and it has only two mode.
• A common example of on-off control is the
temperature control in a domestic heating system.
4. P Controller
• To Understand P Controller We Need a Model

5. P Controller
• The relationship between the error signal and
controller output
m(t)=Kpe(t)+m0
Here , m(t)=Controller output,
e(t)=error
Kp=Proportional gain constant
m0=Controller output at zero error
