A Modified Pid Controller for Controllable Linear Time-Invariang Siso Systems

The objective of this study is to modify the PID controller in such a manner as to widen the stability domain of the controller and at the same time increase its accuracy. This modification has been performed by changing the length of the intergration interval of the PID controller. Using Ziegler-Nichols tuning rules, all simulation results indicate that the performance of the proposed controller is better than that of traditional PID controller.
