摘要 针对一类具有不确定性参数以及状态滞后的线性系统提出滑模控制方案.为求解滑动模态方程选取了一个特殊的坐标变换,并且通过求解线性矩阵不等式来设计切换面和控制器,另外,引入自由加权矩阵来增加线性矩阵不等式的可解性,最后仿真结果证明了所提方法的有效性. Sliding-mode control strategies are presented for a class of linear systems with uncertainties and state delays. To get the sliding-mode equation we introduce a special coordinate transformation. The parameters of sliding surface and controller can be solved through LMIs. Also we introduce some free matrixes to strength the feasibility of the LMIs. Finally a numerical example illustrates the design methods.
