摘　　要：在对通用变频器常用的四类加减速方式分析研究的基础上,提出了一种简单实用的可以根据需要任意设备加减速时间、圆弧时间及目标频率的曲线加减速实现方法,从而能平滑有效地控制异步电动机,减小了电机起动和停止时的电流冲击。The simple and useful method to realize the four acceleration and deceleration pattern common used in universal inverters, based on the analysis and study of them is proposed. This method can control the asynchronous motor smoothly and effectively, and can also reduce the current shock during startup and shutdown.
