Robust Stabilitzation for Uncertain Dynamic Systems with Sector Nonlinearities

讨论一类输入为扇区非线性的不确定系统的渐近镇定问题。在假设系统不确定性满足匹配条件的情况下 ,基于无源性理论用逻辑切换得到了控制规律 ,并给出镇定这类系统的一种新的鲁棒控制方法。仿真算例表明该方法具有良好的控制效果。

The problem of asymptotical stabilization for a class of uncertain systems with sector nonlinear input is discussed. Under the matching condition, the controller is obtained by logic switch base on passivity theory. An example is given to show the effectiveness of the proposed approach.
