Abstract

Predictive torque control has attracted extensive attention due to its advantages of no field orientation, no current inner loop, no parameter setting, direct inverter drive signal without pulse modulation, simple structure, and rapid response. The traditional predictive torque control uses a cost function to control the electromagnetic torque of the motor and the stator flux and limit the switching frequency, which has the problem of cumbersome and complicated weighting factor setting. To reduce the switching frequency and avoid the tuning of weighting factors, a predictive torque control for induction motors based on a circular boundary-limited strategy is designed in this paper. The "|ψ_s|-T_e coordinate system" is constructed with the motor stator flux and electromagnetic torque after the standard unit, and the circular boundary restriction strategy is adopted to reduce the switching frequency and avoid the adjustment of the weighting factor. By comparing with the traditional predictive torque control, this method's control effect and feasibility are verified.
