摘要
针对一类具有未知干扰的输入系统,讨论了一种含有干扰观测补偿的滑模变结构控制设计问题,并采用趋近律的滑模设计方法优化控制律参数,有效地削弱了系统抖振现象,以满足控制系统的鲁棒性和趋近运动动态品质的要求,同时也能改善系统的稳态性能。仿真研究结果表明了该方法的有效性。
In this paper, the problem of sliding mode control (SMC) with disturbance observer is discussed for a class of unknown inputs system. And the reaching law is used to optimize the control law parameter which ensures the dynamic and reliable performance of system. The approach minishes switching gain by compensating disturbance effect, so that the chattering phenomenon that is inherent to variable structure system has been eliminated. The simulation results show that the proposed method is valid.
