Abstract

The state observation and unknown input identification problems are studied for a class of nonlinear autonomous switched systems. A bank of observers are designed using the high-order sliding mode techniques. The robustness of the high-order sliding mode observers is exploited to provide exact reconstruction of the continuous state and the discrete state even in the presence of unknown inputs. The value of the equivalent injection is used for identification of unknown inputs. Simulation results support the proposed method.
