摘要

我们设计了一类具有单调扇形非线性的系统的观测器。所得到的非线性估计误差系统被表示为一个线性系统和一个时变多变量扇形非线性的反馈互连。利用LMI软件，计算观测器增益矩阵以满足圆准则，从而使估计误差为零。在输出反馈控制中加入了新的观测器，并通过实例进行了说明。

Nonlinear observers: a circle criterion design

We design observers for a class of systems with monotone sector nonlinearities. The resulting nonlinear estimation error system is represented as the feedback interconnection of a linear system and a time-varying multivariable sector nonlinearity. Using LMI software, an observer gain matrix is computed to satisfy the circle criterion and, hence, to drive the estimation error to zero. The new observer is incorporated in output feedback control, as illustrated by an example.
