摘要
针对一类状态变量中含有时滞的线性系统,提出了函数观测器设计的一种参数方法。给出了函数观测器存在的充要条件。基于Lyapunov稳定理论和广义Sylvester矩阵方程的完全参数化解,给出了时滞系统函数观测器设计算法。两个数值例子说明了提出算法的简单性、有效性。该方法提供了进一步满足其他性能要求的设计自由度。
A parametric approach to the design of functional observers for a class of linear systems with delays in state variables is proposed. The necessary and sufficient condition functional observers are first established; based on Lyapunov stability theory and generalized Sylvester matrix equations, a design algorithm of observer for a class of linear time-delay systems is then proposed; finally two numerical examples shows the simplicity and the effectiveness of the proposed approach.
