Iterative PID Control Design Approach for Maximizing Proportional Gain

Abstract

This paper presents an iterative proportional-integral-derivative (PID) controller design approach. To achieve the desired control performance, the control designer iteratively increases the proportional (P) and derivative (D) gains. And then, the integral controller is added to the obtained PD controller to reduce the steady-state error. Thus, the proposed approach is easy to implement and effective since it aims to maximize P-gain. Moreover, the stability conditions are presented to explain why stability is ensured while increasing PID gains. Simulations for the motor control system are peformed to validate the effectiveness of the proposed approach.
