Abstract :
A new adaptive fuzzy-logic controller is proposed. The rule base of the fuzzy system is tuned online based on a variable structure algorithm. Both state and output feedback versions of the controller are derived. The output feedback controller utilizes the high gain observer. The stability of both versions of the controller is proved. Simulation results demonstrate a promising performance.
