Design of a PID controller based on a reset compensator using the Clegg integrator

Abstract

In this study, we propose the use of proportional-integral-derivative and Clegg integrator (PID+CI) reset compensators. The CI is a nonlinear integrator based on reset action. PID+CI resets the output of the integrator based on the plant deviation. Thus, this controller is expected to reduce the overshoot of the plant output. This study is devoted to the tuning method of PID+CI reset compensators and also confirms its effectiveness for a second-order plant.
