| 摘 要： | 将模型参考自适应应用于直接转矩控制系统中,取代了传统的积分器,并在此基础上实现了系统的无速度传感器运行。针对2.2kW异步电机,采用MATLAB/SIMULINK软件进行了仿真,仿真结果表明,该系统对电机定子磁链的观测精度高,速度运算比较准确,尤其是在较低转速下仍能保持较高的性能。

| Abstract: | The model reference adaptive system is proposed to replace the classical integrator in the direct torque control system. Based on it, a simple and high perfomance speed sensorless system comes true. This approach has been implemented on MATLAB/ SIMULINK software in a 2.2kw drive. Simulation showsthat this method gives satisfying estimation of stator flux and rotor speed, especially at lowerspeed. |
