Comparison of performance indices of PID controller with different tuning methods

Abstract

Proportional Integral Derivative (PID)-type controller are the most commonly used control algorithm in industry due to their practicality. Two design techniques are presented for tuning the parameters of the controller, Zeigler-Nichols and the Åström-Hägglund method based on certain design specifications. In order to achieve better performances, different combinations of parameters from the two techniques are tested. The proposed method uses proportional and integral gain from Zieglor-Nichols method and derivative gain from Åström-Hägglund method. Response of different combinations of parameters are simulated and compared to show the advantages of the proposed method.
