Abstract: This paper investigates modeling and guaranteed cost control of quantized feedback systems over networks with bounded packet loss. The model of the networked control systems, which appropriately incorporates quantized feedback, is established in terms of robust control which transforms the problem of stabilization of networked control systems with packet loss into the problem of robust stabilization of a class of subsystems. Unlike the quadratic Lyapunov function which is normally used in analyzing networked control systems, this paper presents a new approach that can significantly reduce conservativeness by taking the quantization dependent Lyapunov function. Based on the provided Lyapunov function, a guaranteed cost state feedback controller is derived, which explicitly considers the packet loss process. A numerical example illustrates the effectiveness of the proposed method.1) 本文责任编委 吴立刚 -
