Abstract :
An fuzzy logic controller (FLC) is developed in this paper for the nonminimum phase system. The well-designed fuzzy rules are exploited to resolve the undershoot problem caused by the unstable zeros. A 3rd-order plant with two unstable zeros is used to verify the performance of the fuzzy controlled system. Simulations demonstrate that the proposed fuzzy logic controller can be used to handle the nonminimum phase system
