Fuzzy sliding mode control for non-matching uncertain systems

Abstract:The fuzzy sliding mode control for non-matching uncertain systems is studied. By applying dynamic (compensator) and inequality technique, the sliding mode is designed and the problem of non-matching uncertainty (restraint) is solved. A stability condition of sliding mode with litter conservative is obtained. In order to overcome chatter phenomenon, the fuzzy number model and double quadratic function interpolation algorithm are combined to design a fuzzy sliding mode control law. Simulation results show that this method has stronger robustness against the variation of parameters and disturbance.
Keywords:fuzzy control  sliding mode  dynamic compensator  robustness
