Modeling and Stability Analysis of Multi-rate Single-Side Networked Control Systems

Aimed at a kind of multi-input & multi-output networked control systems with the sensors and controller interconnected by network and the output variable are controlled at different sampling period, its structure and model and stability are studied in this paper. Supposed that the maximum network-induced delay time is smaller than one sample period, the model of the networked Control system is given. Based on estimation theorem of feature value from perturbation theory, the sufficient condition subject to the asymptotic stability of the close loop system is derived.
