Abstract :
The unknown input identification and state observation problems are studied for a class of linear autonomous switched systems. The necessary conditions for the reconstructability of the unknown inputs and states are given. Under structural conditions, it is proposed a robust estimator capable to reconstruct the continuous state, the discrete state and the unknown inputs.
