Optimal control of networked control systems based on time-division algorithm

A new control mode is proposed for networked control systems whose network-induced delay is longer than a sampling period. The proposed control mode can make full use of control information and improve the performance of the system. A time-division algorithm is presented to implement the control mode and mathematical modeling. Markov characteristic of the transfer delay in the system is discussed. Based on Markov chain theory, the stochastic optimal controller is designed, which is shown to render corresponding system mean square exponentially stable.
