| Abstract: | 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. |
