ℋ∞ control of discrete-time switched itô stochastic systems via dynamic output feedback
نویسندگان
چکیده
This paper is concerned with the H∞ dynamic output feedback (DOF) control problem for discrete-time switched Itô stochastic hybrid systems. By applying the average dwell time method and the piecewise Lyapunov function technique, a sufficient condition is first proposed, which guarantees the closed-loop switched stochastic system to be mean-square exponentially stable with a weighted H∞ performance. Then the solvability condition for the H∞ DOF control is also established, by which the DOF controller can be found by solving a set of linear matrix inequalities (LMIs).
