Abstract: In this paper, a new observer-based [H∞] controller design method is developed for a class of time-varying networked control systems subject to high-rate communication network and Round-Robin（RR） protocol over a finite-horizon. The system under investigation involves multiplicative noise, stochastic time-delays and quantization effects. By applying Lyapunov stability theory and Linear Matrix Inequality（LMI） technique, a sufficient condition for the existence of the finite-horizon [H∞] controller is derived. The corresponding parameters of the observer and controller are obtained via resorting to a set of recursive matrix inequalities based on Cone Complementarity Linearization（CCL） method. The proposed controller can ensure both the stability and the prescribed [H∞] performance index of the closed-loop system over a given finite horizon. A simulation example is finally utilized to illustrate the effectiveness of the proposed controller design scheme.
