Abstract :
A practical and functional wireless PID controller, which is based on a measurement estimator is suggested. The estimator acts as an interface between the wireless measurements and the discrete PID controller, and estimates missing measurements when needed. With the suggested structure, no dedicated wireless controller is needed, but the same PID block can be used for both wired and wireless control. The functionality of the suggested control structure is experimentally verified on a flow control loop with Wireless HART and WLAN communication.
