A Unified Observer for High Order Disturbances in Time Series Expansion

摘要：

　　A unified observer of high order disturbances in time series expansion for a class of nonlinear systems was proposed in this paper.The stability of a special observer from selecting the nonlinear weighted function was analyzed for constant disturbance.Then the constant disturbance observer algorithm was generalized to ramp disturbance and high order disturbances in time series expansion by incorporating the higher order integrals.Simulation examples were illustrated to show the effectiveness and advantages of the proposed algorithms.
