Abstract :
In this paper, for a class of switched linear singular systems with linear fractional uncertainty, the robust H∞ control problem is investigated by using a strict linear matrix inequality (LMI) appoach. First of all, for the unforced system, a sufficient condition is given for generalized robust stabilization with prescribed disturbance attenuation level only by switching. Then, the robust H∞ control synthesis via switched state feedback is solved by LMI approach. The obtained results generalize and improve the previous works on switched singular systems and switched state-space systems.
