摘要
针对当前伺服系统采用的角度传感器进行AD采样和换算后得到电机速度,无法很好满足速度实时性要求.同时位置反馈元件线性度低、反馈信号易受干扰,因此导致伺服系统稳定性很难保证。结合目前伺服系统存在速度闭环差、结构转换效率低、抗干扰能力弱等问题,提出一种伺服电机与减速机构、旋转变压器一体化设计的方案。通过试验证明,该伺服系统具有控制精度高(最高可达16bit精度)、抗干扰能力强等特点,符合未来电动伺服系统发展的研究方向。
The current servo system, which obtains motor speed by using the AD sampling of angle sensor, cannot meet the requirements of speed real-time. And as the linearity of the position feed- back element is low and the feedback signal is vulnerable to interference, it is difficult to ensure the stability of the servo system. To solve the problems of current servo system in its speed closed-loop, structural conversion efficiency, anti-interference ability, etc. , an integrated design method of servo motor, reducing mechanism and rotary transformer is presented. The experiment shows that the servo control system presented has advantages of high precision （up to 16bit）, strong anti-interference capacity and so on, and the method meets the requirements of deelopment of the future electric servo system.
