Networked predictive control of Hammerstein systems

摘要：

　　This article mainly deals with the control and stability problems of networked Hammerstein with nonlinear input.A novel predictive controller design method is proposed to offset the effect of network delay and data dropout.The controller gain which depends on the time delay of the feedback channel is time-variant.Since we assume that the state is not measurable,the control signal is based on the state estimated by the observer.As for the nonlinear part of the input,We assume it satisfies a sector constraint and treat it as a input inaccuracy.Theoretical results are presented for the closed-loop stability by modeling the system as time-delay Hammerstein system with nonlinear inputs.A second-order Hammerstein system is implemented to show the enhanced performance of this control method.
