由于系统采用了比例积分调节器(简称PI调节器),使系统在扰动的作用下, 通过PI调节器的调节作用使电动机的转速达到静态无差,从而实现了静态无差。无静差调速系统中,比例积分调节器的比例部分使动态响应比较快(无滞后),积分部分使系统消除静差。-Because the system uses a proportional integral regulator (referred to as the PI regulator), to make the system so that the speed of the motor in the disturbance, the regulatory role of the PI regulator to achieve static difference, in order to achieve a static difference. No static error speed control system, the proportion of the proportional integral regulator of the dynamic response is faster (no lag), integral part to eliminate static error.
