Realization of Stabilizing Network Control Systems with Round-Trip Time Delays

The purpose of this paper is to present a stable network control design with uncertain time-varying communication delays. In the typical networked control systems (NCSs), there are inherent plant delays and network delays. It has been know that time delays may not only degrade the system performance, but also destabilize the controlled plant. To alleviate the influence resulting from time delays while maintaining performance, we propose a compensating scheme which consists of two compensators-a fuzzy-PID controller and a neuron network compensator. The proposed design has also been experimentally verified to show its effectiveness and superiority.
