Lab 2, Analysis and Design of PID Controllers IE1304, Control Theory 1 Goal The main goal is to learn how to design a PID controller to handle reference tracking and disturbance rejection. You will design the controller and analyze its characteristics (settling time, stability, overshoot, steady-state error). The PID controller is implemented in software, written with ISaGRAF which is a development environment for a Programmable Logic Control, PLC While designing a PID controller, the general rule is to add proportional control to get the desired rise time, add derivative control to get the desired overshoot, and then add integral control (if needed) to eliminate the steady-state error. Effects of PID Controller:-Its purpose is to improve stability as well as to decrease Steady State Error control loop feedback mechanism. A proportional-integral-derivative controller ( PID controller or three-term controller) is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control Basic PID controller is designed and is adopted to control the MAV, a modified techniques incorporating ISA-PID is designed to reject disturbances. The PID parameters are determined to be reduce the ris A PID (Proportional Integral Derivative) controller works by controlling an output to bring a process value to a desired set point..

A new design scheme of PID controllers was presented based on dynamic linearization models. First, an adaptive PID control rule was proposed. By formulating the closed-loop systems as an interconnection system, a rigorous Lyapunov-based proof of stability was given to ensure the convergence of tracking error when the initial state and PID gains lie in a compact set PID controller design using Simulink MATLAB In this tutorial, a simple PID (Proportional Integral Derivative) is designed using MATLABs' Simulink.

In process industries, most of the control loops (typically 90-95 percent) are of PID type. These controllers receive inputs from sensors, meters, etc. and depending on PID control function they deliver output control signals to the controlled or manipulating devices such as relays, actuators, etc
