非线性联级系统的鲁棒镇定

On roboust stabilization of nonlinear cascaded system

对于一类带有不确定参数的非线性联级系统的鲁棒镇定问题。当不确定参数为零时该系统由一光滑可镇定系统与一般非线性系统的联级。在无需匹配条件下 ,给出其鲁棒镇定的充分条件 ,扩展了现有的非线性鲁棒镇定的某些结果。

In this paper,we consider one kind of roboust stabilization of nonlinear cascaded system with indefinite parameter.When the indefinite parameter equals zero,this system is cascaded with a smoothing stabilized system and a nonlinear system.If it needn't matching,we give the sufficient condition about the roboust stabilization of this system and spread some conclusion about the robust stabilization of nonlinear system which existed.
