-
摘要: 针对一类具有不匹配不确定的MIMO系统, 在用理想系统(即不存在不确定性时的系统) 所对应的代数RICCATI方程的解来构造滑动模态超平面的基础上, 提出了一种具有连续性质的变结构鲁棒控制算法, 该算法可确保系统滑动模态运动满足实际稳定性。最后以船舶航向控制系统为例, 进行了变结构鲁棒控制自动舵设计, 通过仿真研究可见, 所提出的算法是有效的Abstract: Based on the method for constructing sliding mode hyperplane with the solution of the algebraic RICCATI equation of normal system, a variable structure robust control algorithm with continuous performance and globally practical stability with respect to the sliding mode of the system is presented for a class of uncertain MIMO systems with the absence of matching assumptions.An example illustrating the method described is included.
