针对不确定性由增益有界的摄动函数表示的非线性系统,讨论了状态反馈鲁棒镇定问题.结果表明,如果所讨论的系统具有鲁棒最小相位特性,且其标称系统相对阶为1,则反馈控制律可以通过构造满足本文引理条件的正定函数得到.%This paper discusses the robust stabilization via state feedback for uncertain nonlinear systems. The uncertainty is described by gain bounded perturbation function on the state variables. The main result shows that a feedback control law can be obtained by constructing a positive definite Lyapunov-like function, if the considered system is of robust minimum-phase and its nominal system has relative degree one.
