First, both state and output transformations are considered to deal with the unknown inputs of the switched system, and a reduced-order switched system that eliminates the effects of unknown inputs is constructed. Second, for each reduced-order subsystem, a corresponding observer is designed, and multi-observers for the reduced-order switched system are developed. Next, a kind of active mode identification method is proposed by minimizing the output residual norms that are derived from multi-observers. Third, based on the identified active mode, the continuous state estimation of the original switched system is approximately realized. Finally, a simulation example is given to illustrate the effectiveness of the proposed methods.
