摘　　要：采用模型预测控制对异步电机的定子电流进行控制,获得最优的定子电流。为了降低系统硬件成本,增加系统环境适应性和可靠性,采用无速度传感器技术获得转速。通过扩展卡尔曼滤波算法得到电机转速信息。仿真结果及实验结果表明,所提出的无速度传感器模型预测控制方法在较宽的调速范围内动、静态性能优良。Model predictive control strategy was used to control asynchronous motor stator current for obtaining the optimal stator current.Speed sensorless technology was adopted to get speed in order to reduce hardware costs as well as increasing system environmental adaptability and reliability.Motor speed information was obtained through extended Kalman filter algorithm.The simulation and experimental results show that the proposed speed sensorless model predictive control method has good static and dynamic performance over a wide speed range.
