一类不确定仿射非线性系统的动态输出反馈全局镇定(英文)

Global Stabilization via Dynamic Output Feedback for a Class of Uncertain Nonlinear Systems

本文研究带有非匹配不确定性的ＳＩＳＯ 及ＭＩＭＯ 仿射非线性系统的动态输出反馈镇定问题，在要求标称系统为双曲极小相位及系统不确定部分满足一定条件下，构造出了输出反馈形式的动态补偿器．该动态补偿器使相应闭环系统在Ｌｙａｐｕｎｏｖ 意义下全局渐近稳定．

In this paper,the problem of global stabilization for SISO and MIMO affine nonlinear systems with mismatched uncertainties are investigated.The robust controllers in the form of dynamic output feedback are constructed,which make the controlled uncertain plants be globally asymptotically stable in Lyapunov's sense. A simulated example is given to show the effeciency of the proposed method.
