A novel robust control strategy for industrial systems with time delay

This paper proposes a novel controller synthesis for industrial systems with time delays. The aim of this control strategy is to extend the well known RST controller design to systems with dead-time. The main advantage of this technique is to propose a simple design of the controller with one tuning parameter. The proposed controller uses the Smith predictor in addition to the the RST controller. This solution can be used for stable, unstable and integrating systems. The proposed controller is implemented into a Schneider PLC for a field test.
