LQG control networked controls of MIMO networked control system

The LQG controller for a class of MIMO networked control systems with bandwidth constraints is studied. A pair of periodic communication sequences are proposed to reduce the effect of bandwidth constraint. Under the proposed model, we amend the extended plant model to include ZOH for inputs, by augmenting the state to include those inputs which are not updated. The Kalman filtering and LQ optimal control for NCSs can be formulated as a standard LQG problem for an equivalent periodic system. Furthermore, the controller gain is obtained by using dynamic programming method. At last, a numerical example is given to verify the effectiveness of the result presented in this paper.
