Delay-independence Stability Analysis of MIMO Networked Control Systems with State Feedback

A kind of MIMO networked control system, in which each state signal of object controlled is obtained by an independent sensor and then sent to a single controller through a network, and also each output signal of the controller is sent to an independent actuator through the network, is studied in this paper. The figure of its structure is given, and its mathematic model is set up. Based on the Lyapunov theory, the delay-independence condition subject to the stability of the MIMO networked control system is derived. A numerical example given testifies that the method presented in this paper is feasible.
