Observer design for MIMO networked control systems

The observer design is described for a class of MIMO networked control systems. Consider a MIMO networked control system within time-driven sensor nodes and controller node, the effect to the information transmission, which caused by network induced delay and data packet dropout, is analyzed firstly. And a observer is proposed to compensate the delay and packet dropout. Then based on separation theory, with the multi-Lyapunov functions and linear matrix inequality method, the sufficient condition on the asymmetric stability of the observer error system is given, together with the design approach of the gain matrix. Finally, a numerical example is given to validate the method.
