摘要
针对一般滑模变结构控制算法的不连续和不可导 ,用一种连续且可导的控制算法来近似 ,并分析了整个控制系统的鲁棒性。用数字方法讨论了这一近似算法的有效性和近似算法参数选择问题 ,得到了有益的结果。
An approximate sliding mode variable structure controller is presented in this paper. The obtained controller is a continuous and differentiable one. The robustness of the closed loop system is analyzed with the Lyapunov functional method. The effectiveness and the choice scheme for the parameters in the controller are studied with a great deal of simulation.
