Abstract
The unknown input identification problem is studied for a class of nonlinear autonomous switched systems. It is proposed a robust observer which is capable of reconstructing the continuous state and the discrete state in the presence of unknown inputs. On the other hand, it is provided a method for identification of unknown inputs using the high frequency equivalent output injection. Simulation results support the proposed method.
