Abstract
- This paper proposes an improved model predictive torque control (MPTC) method for an open-end winding permanent magnet synchronous motor (OEW-PMSM) with reduced computation time. First, a basic predictive torque control algorithm is derived, which is based on the discrete system model and cost function. Then, a direct torque control (DTC) based switching table is developed to reduce the computation time. In addition, a weighting factor elimination method is adopted to avoid the tuning work, which is based on the equivalent reference vector of the reactive torque. Also, the optimal switching state selection strategy based on the principle of least switching losses is introduced. Simulation results are offered to verify the proposed method.
