研究了一类时变时滞依赖非线性系统的观测器设计问题.这个系统考虑了时变时滞状态和非线性干扰,并且这个非线性项满足全局Lipschitz条件.对于允许的时滞和非线性干扰,利用一个变换和不等式技巧,将观测器的设计,误差方程的稳定性归结为一个矩阵不等式,给出了观测器增益阵的解析式和误差方程全局渐近稳定的条件,一个例子说明了所提定理的可行性.

Observer Design Based on Time-Delay Systems with Non-Linear Disturbance

In this paper,the observer design problem is studied for a class of time-delay systems with time-varying delays. The systems under consideration is subject to delayed state and non-linear disturbances, and the non-linear is assumed to satisfy global Lipschitz conditions. For the admissible time-delay as well as non-linear disturbances, an time-delay integral transformation and a matrix inequality method are developed. The design of observer and stability of error systems can be represented as a matrix inequality, matrix of observer gain and condition of global asymptotically stable of error systems are obtained.An example is included to illustrate the pratical applicability of the proposed theory.
