Abstract (EN)
In this thesis, a new control scheme is presented for the robust speed control of electrical drives. The proposed control method is based on Type-2 Fuzzy Logic and Sliding Mode Control (SMC) techniques. In the design of the proposed controller, Reaching Law Control (RLC) approach (which is a SMC design method) is used. Takagi-Sugeno-Kang (TSK) fuzzy system and interval type-2 fuzzy sets are preferred due to their suitability for control applications. Non-singleton fuzzification is employed because of its effectiveness on uncertainties. The control performance is tested under inertial-frictional variations and external load torque disturbances. In order to show the effectiveness of the new control approach, simulation and experimental results of the SMC and Type-2 Fuzzy SMC (T2FSMC) systems are presented together. Keywords : Type-2 fuzzy logic, sliding mode control, reaching law control, drive control, robust control, speed control.
