H∞ finite-time composite anti-disturbance switching control for switched systems.
The paper centers on the H∞ finite-time (FT) composite anti-disturbance switching control (ADSC) issue for switched systems (SSs) suffered from multiple disturbances, the unavailable modeled disturbance and the available un-modeled disturbance. The aim is to arrive at the multiple disturbance suppression in FT. A switching estimator is firstly constructed to observe the modeled disturbance combined with the unavailable system state. A switching controller and a switching law are then co-established to restrain the multiple disturbances in the SSs. A condition is attained to ensure that the H∞ FT composite ADSC issue for the SSs is solvable, even the issue is not solvable for subsystems. A verification example is served to text the reasonability of the developed theory.
