Nonlinear observer design using piecewise-linear functions based approximations

综合分片线性函数模型辨识/逼近和鲁棒观测器设计方法,研究了一大类非线性鲁棒观测器设计方法.所提出的算法能有效解决非线性系统的辨识/建模问题,并保证在一定的逼近精度下观测误差可以控制在一定的范围内,且观测误差随着逼近精度的提高而减小.

This paper studies the observer design problem for a large set of nonlinear systems using pievewise-linear functions based approximations and robust observer design techniques. The proposed algorithm can effectively solve the nonlinear systems identification/modeling problems, and also show that the observer error is bounded if certain approximation preciseness is guaranteed. Moreover, the observer error will decrease when the approximation preciseness increases.
