| 摘 要： | 在很多以三相异步电动机为动力源的应用场合，往往对电机输出转速的精度要求不高，但要求电机能够迅速的启动和制动。针对这一问题，本文通过对三相异步电动机机械特性的分析，提出了利用转子磁链观测器来采样电机当前速差，通过调整速差来调节启动和制动力矩的控制策略，并在基于TMS320LF2407A DSP的硬件平台上实现。经过实际试验验证，明显加快了电机的启动和制动动态过程，效果明显，证明此方案可行。

| Abstract: | In many applications of three-phase AC asynchronous motor to the power source, the control requirements focus on the rapid start-brake process of the motor, instead of the precision of the speed. With the research of the mechanical character of the AC motor, a control strategy for the start-brake torque controlled by adjusting the difference of speed which can be sampled through rotor-magnetism-chain-observer was proposed and realized by hardware platform based on TMS320LF2407A DSP. The experimental results show that the control strategy can expedite the start-brake dynamic process of the AC motor remarkably and the control schemes of the start-brake processes are feasible. |
