| Abstract: | A sensorless model predictive torque control （MPTC）strategy is proposed for three-phase permanent magnet synchronous motor （PMSM）drive system with MRAS observer.By making use of techniques of MRAS,a MRAS observer is designed to estimate speed.In order to reduce the torque ＆ flux ripples and improve control performance,MPTC strategy is employed. Numerical simulation shows that the proposed MPTC with MRAS observer achieves satisfactory control performance for torque ＆ speed control,and thus validates the feasibility and effectiveness of the proposed scheme. |
