摘      要：This letter presents an approach to deal with robust Hstate and input hybrid estimation for continuous linear time-varying systems,where norm-bounded parameter uncertainty is appeared in the state and output matrices and a known input is incorporated in the state-space *** known input will influence the estimation due to parameter *** differential game theory approach,a sufficient solvable condition for the problem is proposed as well as a design method for the optimal *** with those based on nominal systems,the proposed approach significantly improves the estimator’s robustness to parameter uncertainty and known *** simulation example about a second-order resonant system illustrates the effectiveness of such an approach.
