Abstract

This paper mainly studies stability and optimal control for networked control systems with the real-time setup of time-driven sensor, event-driven controller and actuator, and with the assumption that network-induced delay is no longer than certain known times of sampling period. The modeling of this class of networked control systems is given. Then, preliminary stochastic stability analysis of it is presented. Finally, based on stochastic optimal control theory an LQG control scheme is provided. Much work needs to be continued for future research.
