摘要
针对一类同时具有凸多面体不确定性和非线性扰动的变时滞系统,这里的非线性项满足一种特殊的线性界,首先利用线性矩阵不等式给出系统强鲁棒稳定且满足H∞性能指标的充分条件;然后设计状态反馈鲁棒H∞控制器;最后给出仿真算例,验证了所得结果的可行性与有效性.
Robust H control problem of nonlinear systems with time-varying delay and polytopic uncertainty is discussed. The nonlinear condition satisfying a type of especial linear bound is assumed. By using the linear matrix inequality technique, a sufficient condition for nonlinear time-delay systems, which is asymptotically stable and satisfies H performance, is given, and the explicit design method of the robust H controller is obtained. Finally, an numerical example is supplied to clarify the feasibility and effectiveness of the proposed results
