| 摘 要： | 开发了基于高性价比DSPMC56F8013的低成本异步电机控制平台，研究了一种基于定子磁场定向的异步电机无速度传感器控制算法。该算法结构简单，易于实现，对电机参数依赖性小。文中提出定子磁链校正因子，用于补偿低速运行时由于一阶低通滤波器的使用而造成的定子磁链观测误差。新颖的转速调节器，保证电机在动态过程中以最大转矩运行。系统仿真和原理样机的试验结果表明，整个控制系统具有良好的动态和稳态性能。

| Abstract: | The control platform of the induction motor (IM) with low costs is developed by using DSP MC56F8013 with a good performance/price rtaio. The control algorithm for the speed sensorless IM is studied based on the stator flux orientation (SFO). The algorithm structure is simple to be implemented and cannot be influenced by motor parameters. The improved stator flux estimation is used to compensate errors caused by the low pass filter (LPF). A new speed regulator is designed to ensure the system working with the maximal torque in the transient state. The system simulation and the prototype experiment are made. Results show that the control system has good dynamic and static performance. |
