A novel anti-windup compensator based on fuzzy logic

With respects to the windup problem exist in control system with Integral Saturation, a kind of fuzzy logic-based compensation method is proposed. Simulation is done to the designed fuzzy compensator and conventional compensator based on back calculation respectively. Simulation results show that the proposed fuzzy method gives generally better tracking performances than the back-calculation. The designed fuzzy compensator has advantages of simple structure and easy to realize.
