摘要
本文首先研究了一类3--D非线性系统的稳定性问题,在此基础上,利用秩条件和线性矩阵不等式(LMI)方法,得到了这类系统的渐近函数观测器存在的充分条件,并给出了函数观测器的设计方法.最后,通过算例来说明这种方法是可行且有效的.
This paper firstly studies the stability condition for a class of three-dimensional (3-D) nonlinear systems,and based on this,a sufficient condition for the existence of an asymptotic functional observer is given in terms of a rank condition and a linear matrix inequality (LMI).A systematic design method is then presented for the design of functional observers.Finally,two examples are provided to illustrate the effectiveness of the proposed design method.
