| 摘 要： | 应用指数趋近律的方法为一类Lorenz混沌系统设计了滑模控制器.考虑系统所受外部扰动且其界参数未知,引入了简单的自适应律,使其能对外部扰动的界参数进行在线估计.为解决滑模控制系统中的滑模抖振问题,同时保证系统的暂态性能,通过模糊规则来调节指数趋近律的参数,得到了一类自适应模糊滑模控制器.仿真结果表明该控制方案的可行性.

| Abstract: | By using the exponential reaching law technology, a sliding mode controller is designed for Lorenz chaotic system subject to an unknown external disturbance.Considering the unknown disturbance,an adaptive law is introduced to adaptively estimate the parameters of the disturbance bounds.Furthermore,to eliminate the chattering phenomenon in the discontinuous switch controller,and to guarantee system transient performance,a new adaptive fuzzy sliding mode controller is designed.The results of simulation verify effectiveness of the proposed control scheme. |
