Abstract [en]

Network-induced delay, data packet drop-out and perturbation are common problems for networked system. The designing of quantized feedback H∞ controller, focusing on the above problem was studied. In this general model, two logarithms were quantized used for the quantizing of control signal and status signal, and the sufficient condition for the asymptotical stability of the network control systems and the design of quantized feedback controller was proposed according to the Lyapunov stability theory and linear matrix inequality. The quantized feedback controller can make the systems asymptotically stable and meet H∞ performance. The design is confirmed to be efficient by the simulation result.
