研究一类多输入多输出非线性系统的全局输出反馈镇定问题.基于Lyapunov稳定性理论,提出一类非线性系统的输出反馈控制器设计的新方法,给出保证闭环系统全局渐近稳定的新的充分条件.最后,仿真实例验证了所得结论的有效性.

The problem of global stabilization of a class of MIMO nonlinear systems by output feedback is considered. Based on the Lyapunov stability theory, a new approach of output feedback controller design for a class of nonlinear systems is proposed. The sufficient condition that guarantees the closed-loop system is globally asymptotically stable is obtained. Finally, an illustrative example is given to demonstrate the effectiveness of the proposed method.
