一类非线性系统观察器设计

A New Class of Nonlinear Observer Designing

对于非线性有界连续可导系统的观察器设计是观察器设计的难点之一。非线性系统一般是不具备分离属性。这加剧了观察器设计的难度。利用处理轨迹收敛的收缩理论,把控制器系统和观察器系统看作一个整体方式处理观察器设计问题,给出了非线性系统的观察器设计的一个充分条件,并把它扩展到了离散非线性系统。

There is a nodus to design an observer for nonlinear bounded continuous differentiable system. Nonlinear system usually does not possess the separate property. It worsens the straits. Using contraction theory dealing with track convergence, cope with controller and observer as a whole, bring forward a sufficient condition to design nonlinear system.
