Cooperative Networked Control with Gain Switching Observer

This paper considers a networked synchronization of multiple subsystems for cooperative control. When a system sends out local measurement signals to others, transmission delay can take place. We assume that the amount of the transmission delay can be calculated at the receiving instance by using the information of the time-stamp of each packet. Based on this information, the effect of the delay is compensated. Specifically, we design a gain switching observer via LMI (Linear Matrix Inequality) technique for multiple purpose optimization. An experimental result of synchronization of a mini plant with 3 DC-motors is shown to demonstrate its practical effect on the transmission delay.
