摘要
在低速直驱伺服系统中,由于速度过低,加上光电编码器精度的局限,会导致速度信号产生阶跃,从而无法精确控制伺服电机速度值。本文基于传统伺服系统的控制策略,采用了如今先进的光电编码器反馈角度,通过软件观测实现计算,重构出精确的电机转子位置观测值,从而获得连续的电机转子角度给定量,降低编码器精度不高的影响。该实验运用matlab进行仿真测试结果,仿真结果表明,该方法简单有效,有较好的动态性能和控制效果。
In the low speed direct drive servo system, due to the low speed and the limitation of the accuracy of the photoelectric encoder, the speed signal may cause a step, and thus the servo motor speed value cannot be accurately controlled.Based on the control strategy of traditional servo system, this paper adopts the advanced feedback angle of photoelectric encoder, realizes calculation through software observation, reconstructs the accurate motor rotor position observation value, thus obtains the continuous motor rotor angle given, and reduces the encoder. The accuracy is not high. This experiment uses matlab to carry on the simulation test result, the simulation result shows this method is simple and effective, has a better dynamic performance and control effect.
