【Abstract】 The lifting technique to derive the lifted state-space models for nonuniformly periodically updated is usesd and periodically sampled multirate systems.Based on the Kalman estimation principle,the state estimation algorithm of the lifted state-space models is derived,by minimizing the estimation error covariance matrix.Finally,an example is given to validate the algorithm proposed.更多还原
