Sliding-Mode Observers Design of Uncertain Systems Algebraic Based on an Approach
摘要
Abstract
This paper considers the problem of designing sliding-mode observers for linear invariant systems with unknown inputs when the observer matching condition is not satisfied. The unknown inputs can be divided into two parts, one is matched unknown inputs and the other is unmatched unknown inputs. Using an algebraic unknown inputs modelling technique, the mismatched part can be expressed as a dynamical system. Therefore, an augmented system consisting of the original system model and the unmatched unknown inputs model is constructed such that the observer matching condition can be satisfied. For the augmented system, a sliding-mode observer is designed which is able to asymptotically track the original states. The simulation results to a single flexible joint robot link model demonstrate the effectiveness of the proposed approach.关键词
