摘要
为提高无刷直流电机(BLDC)位置伺服系统动静态性能,将柔性变结构控制系统应用于无刷直流电机位置跟踪系统中。并在柔性变结构控制基础上加入变饱和控制状态,从而将伺服系统的跟踪误差进行分类处理,对所设计的控制器分别作了正弦波和方波跟踪的仿真及实验验证。结果表明,该方法明显增强了无刷直流电机伺服系统的调整时间和跟踪精度。
To improve the dynamic and static performance of position servo system of brushless direct circuit motor（BLDCM）,a soft variable structure control with variable saturation proposed.Variable saturation item is introduced on the base of the soft variable structure control,so the error can be dealt with is different ways.The simulation and experiment results show that the controller designed by the proposed method obviously improves the dynamic and static performance settling.
