| 摘 要： | 针对一般非线性系统,在它的自治动态是稳定的条件下,应用Lyapunov方法获得它可全局渐近稳定的充分条件,同时在系统函数是解析的情况下,基于输出反馈控制律,构造出了类Luenberger观测器,使得闭环系统的平衡点全局渐近稳定.

| Abstract: | This paper deals with general nonlinear systems whose free dynamics are stable. We use Lyapunov method to obtain a sufficient condition that can globally stabilize that system.On the condition that systems function is analytic,we design a Luenberger-observer-like based on the output feedback control law which guarantees the closedloop systems are asymptotically stable on the equilibrium point. |
