基于DSP的一体化交流伺服系统研究和实现

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。

Research and Implementation of Integrated AC Servo System Based on DSP

The current servo system uses the AD sampling of angle sensor and obtained motor speed, this method cannot satisfy the requirements of real-time colleague. At the same time, the low linearity position feedback element and the easily interference of the feedback signal , it is difficult to ensure the stability of the servo system. In this paper, combined with the current speed of the closed-loop servo system has poorly structure low conversion efficiency,anti-jamming ability and weak problem ,the integrated designation of a servo motor ,a reduction mechanism and method resolver is presented . The experiment shows that the servo control system having high precision(up to 16bit),anti-interference ability and other characteristics, conform to the future research direction of electric servo system development.
