PID Controller Design via Root Locus | PID Controller Design | Steady State Error | Transients

This lecture is about the design of Proportional Integral Derivative (PID) Controller via root locus. You'll study how to how to modify the trasnients specifications of the closed loop system by adding proportional derivative controller, PD Controller, by placing the dominant pair of poles at required position either by adjusting the gain or by reshaping the root locus. The transients specifications like rise time, peak time, percent overshoot, and settling time are changed as per requirements. Further you can achieve zero steady state error by adding PI controller. In this a pole is added at origin then a zero is placed near to the origin. In the design process of PID controller two poles and a zero is added to the closed loop system. This can also be implemented by proportional controller, differential / derivative controller and intigral controller. #control_system #pi #pd #lead #lag #leadlag #controller #design #transent #overshoot #transients #peak #time #settling #time #rise #time #ideal #compensator #root #locus #steady #state #error #zero #error #reduced #error
