A Unified Anti-Windup Technique for Fuzzy and Sliding Mode Controllers

Radu Emil Precup, Marius L. Tomescu, Emil M. Petriu

Abstract


This paper proposes the unified treatment of an anti-windup technique for fuzzy and sliding mode controllers. A back-calculation and tracking anti-windup scheme is proposed in order to prevent the zero error integrator wind-up in the structures of state feedback fuzzy controllers and sliding mode controllers. The state feedback sliding mode controllers are based on the state feedback-based computation of the switching variable. An example that copes with the position control of an electro-hydraulic servo-system is presented. The conclusions are pointed out on the basis of digital simulation results for the state feedback fuzzy controller.

Keywords


Anti-windup technique, electro-hydraulic servo-system, fuzzy control, saturation, sliding mode control, digital simulation.
