摘　　要：通过对动态速降的研究 ,提出了几种解决动态速降的方法 ,分别是附加速度直接去掉法、附加速度斜率去掉法、用速度环双调节器的电流记忆法。经过仿真和实验比较 ,发现电流记忆法是最佳的一种方法 ,用此方法可以基本实现无速降 。Several ways to minish droop of motor rotate when load is added suddenly are presented, and the advantages and shortcomings are compared. These method can be described below: directly withdraw annex rotates , withdraw annex rotates by ramp ,current memory by using two speed controller.The simulation and experiment show that current memory is the best method among those,and nearly has no speed droop during suddenly load_added.
