摘要 针对三相永磁同步电机驱动系统,提出了一种无速度传感器模型预测转矩控制方法.基于模型参考自适应技术设计了观测器,以精确估算转子速度;为了减小转矩和定子磁链波动、提高系统动态和静态响应特性,采用了模型预测控制策略.仿真结果表明所提方法可以使PMSM驱动系统达到满意的控制效果,从而证明论文控制策略的有效性和正确性. 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.
