This paper presents a predictive direct torque control (PDTC) system with discrete multiple vector voltage (DMVV) and fuzzy hysteresis for a three-phase induction motor. A fuzzy hysteresis controller is proposed to establish a DMVV for estimating both flux and torque errors, which are the membership functions of the fuzzy system. DMVV switching timing ensures that an appropriate voltage vector is...
This paper presents a hybrid variable structure control scheme for nonlinear systems. A hard variable structure control is constructed firstly for achieving uniform ultimate boundedness control. Then, a soft variable structure control using fuzzy logic is incorporated to help improve dynamic responses when trajectories enter into the ultimate bound. For practical consideration, we added a GA-based...
