Co-design of dynamic scheduling and quantized control for networked control systems

A novel co-design scheme of dynamic scheduling strategy and quantized control for a class of time-delay networked control system with communication constraints is presented in this paper. Sufficient condition of bit rate is given to guarantee the convergence of quantization error by Lyapunov stability theory. The networked control system is modeled as a discrete-time switched system under the effect of Try-once-Discard (TOD) dynamic scheduling strategy and time-varying quantization, and a state feedback controller design method is given to guarantee asymptotic stability of the closed-loop system by using LMI techniques. Finally, two simulation results demonstrate the effectiveness of the proposed method.
