摘　　要：电动伺服系统在设计过程中,由于谐振、噪声、稳定性等问题的影响,系统回路增益和带宽都受到了限制,这导致系统扰动响应变差。针对这一问题,研究了使用加速度反馈来提高扰动响应,通过状态观测器来获取加速度。最后通过仿真,验证了所提方法的有效性。In the design process of electric servo system,due to the influence of resonance,noise,stability and other problems,the gain and bandwidth of the closed-loop system are limited,which leads to the deterioration of the system disturbance response.To solve this problem,this paper studied the use of acceleration feedback to improve the disturbance response,and the acceleration was obtained by the state observer.Finally,the effectiveness of the proposed method was verified by simulation.
