Quantized feedback stabilization of a class of networked control systems with delay and packet dropout

In this paper, the problem of quantized feedback stabilization for a class of networked control systems with time delay and packet dropout is investigated. First, a primitive quantizer is applied to the communication channel and the lower bounds of bit rate is given to guarantee convergence of quantization error. Second, dynamic quantization error is represented by quantization range via coordinate transformation, then stabilization problem of closed-loop networked control systems is studied and a state feedback controller design method is given to guarantee the closed-loop system mean-square stable through Lyapunov stability theory and linear matrix inequality techniques.
