PID control has been developing for improving control performance. To enhance the PID control, this paper describes a design method using the maximum sensitivity of a control system because robust stability can be designed by the maximum sensitivity. In this paper, load-disturbance performance and set-point one are optimized, respectively, and then, PID parameters are optimized for combined performance such that desired robust stability is achieved. Finally, to demonstrate its effectiveness, simulation results are shown. © 2013 The Institute of Electrical Engineers of Japan.
