步进电机的控制为开环控制，启动频率过高或负载过大易出现丢步或堵转的现象，停止时转速过高易出现过冲的现象，所以为保证其控制精度，应处理好升、降速问题。交流伺服驱动系统为闭环控制，驱动器可直接对电机编码器反馈信号进行采样，内部构成位置环和速度环，一般不会出现步进电机的丢步或过冲的现象，控制性能更为可靠。

   步进电机从静止加速到工作转速（一般为每分钟几百转）需要200～400毫秒。交流伺服系统的加速性能较好，以松下MSMA 400W交流伺服电机为例，从静止加速到其额定转速3000RPM仅需几毫秒，可用于要求快速启停的控制场合。

   综上所述，交流伺服系统在许多性能方面都优于步进电机。

   3.0 交流伺服系统的分类

   交流伺服系统根据其处理信号的方式不同，可以分为模拟式伺服、数字模拟混合式伺服和全数字式伺服；如果按照使用的伺服电动机的种类不同，又可分为两种：一种是用永磁同步伺服电动机构成的伺服系统，包括方波永磁同步电动机（无刷直流机）伺服系统和正弦波永磁同步电动机伺服系统；另一种是用鼠笼型异步电动机构成的伺服系统。二者的不同之处在于永磁同步电动机伺服系统中需要采用磁极位置传感器而感应电动机伺服系统中含有滑差频率计算部分。若采用微处理器软件实现伺服控制，可以使永磁同步伺服电动机和鼠笼型异步伺服电动机使用同一套伺服放大器。
