摘要
针对BLDCM位置伺服系统的参数不确定因素,提出一种基于扰动动态补偿的组合趋近律,探讨该系统的离散变结构控制器。在控制器的作用下,理论上获证该系统的稳定性。实验结果显示系统输出对电动机的负载转矩和转动惯量的摄动具有较强的鲁棒性,达到了降低系统的抖振和提高控制精度的目的,有效改善了系统的控制质量。
A combinational reaching law, based on dynamic disturbance compensation, was put forward for solving parametric uncertainty of the BLDCM position servo system, while a discrete variable structure controller was derived to control the system. With the help of the controller, the system was demonstrated to be stable theoretically. Experimental results show that the output of the system is robust with respect to the disturbance of the load torque and inertia and achieves the goal to reduce vibration of the system and to improve the control quality effectively.
