Design of Z-N Tuned PID Controller for Higher Order System | Original Article

ABSTRACT:

This Paper presents the design of Z-N-Tuned PID Controller, to realize governor action in a power generation plant to improving the dynamic characteristics. Proportionalintegral-derivative (PID) controllers are widely used in industrial control system because of the reduced number of parameters to be tuned. The PID control method is most flexible and simple method. This method is more popular among all control methods. The conventional PID controller is replaced by Z-N tuning PID controller, to make them more general and to achieve minimum steady-state error, also to improve the other dynamic behavior (overshoot). The self-tuned proportional integral derivative (PID) controllers are designed for applications where large load changes are expected or the need for extreme accuracy and fast response time exists.
