Increased availability of low-cost electronics has created a new breed of control system components; so called "smart" components, which can perform control responsibilities in the actuator and sensor components as well as in the controller. "Smart" components can communicate bi-directionally in networked control systems. We identify opportunities for improving control system performance and design due to the decentralized, yet more connected, nature of these systems. Current research on

This paper investigates the potential benefits of bi-directional communication in a feedback control loop for improving component swapping modularity of the feedback control system. The problem formulation is presented, for the first time, and also illustrated using a driveshaft speed control example.
