A linear quadratic Gaussian (LQG) stochastic optimal control was developed for networked control systems with network-induced delays longer than a sampling period using a time-division control mode. The control mode uses new information to improve the system performance. A stochastic mathematical model is obtained for the networked control system. The Markov characteristics of the system transfer delay are analyzed to develop a Markov chain theory-based LQG stochastic optimal controller for when the system has full state information. Simulations verify that this time-division control mode prov...
