| 摘 要： | 滑模趋近律及滑模增益的选择直接影响滑模控制的鲁棒性和滑模控制导致的抖振。将一种新的变指数趋近律滑模变结构应用于永磁同步电机伺服系统的位置控制,并结合一种新颖的滑模增益设计方法来改善滑模控制的鲁棒性,削弱滑模变结构的抖振。通过利用位置信号误差和滑模增益之间的非线性关系,给出了这种新颖滑模增益的设计方法。应用Matlab编程对永磁同步电机伺服系统的位置控制效果进行了仿真,其仿真结果表明该滑模控制方法不仅有效抑制了滑模变结构的抖振,同时增强了控制系统的鲁棒性。

| Abstract: | The sliding rate reaching law and sliding gain choice directly influence the sliding mode control and robustness of the sliding mode control result of chattering.Used a new variable exponential rate reaching law sliding mode variable structure in PMSM's servo system,combining the position control is a novel design method of sliding gain to improve the robustness of sliding mode control,weaken the sliding mode variable structure of chattering.By using position signal error and sliding gain the non-linear rel... |
