Sliding mode based repetitive control for improved reference tracking

Abstract

A sliding mode based repetitive control system is proposed, to improve reference tracking performance, as well as compensate output disturbances. The design algorithm is based on the concept of sliding mode controller (SMC), feedback controller, and modified repetitive controller (MRC). With two tuning parameters, the sliding mode based RC provides a simple and convenient method to solve the complex engineering problems. The comparison study was conducted to demonstrate the effectiveness of sliding mode based RC over state feedback based RC.
