Feedforward tuning rules

Feedforward control from measurable disturbances provides a possibility to make control actions before any disturbance response has occurred in the process output. This fact makes it a very powerful complement to the feedback controller. When the feedforward compensator is realizable, the effects of the load disturbance are eliminated from the process output. However, the ideal compensator is usually non-causal, and the system performance is highly affected. Thus, modifications to the classical compensator structure are required to account for this problem. This website summarizes a research line about this topic, where new and simple tuning rules for feedforward compensators have been developed. The contributions presented here are thanks to a strong collaboration with Tore Hagglund, Manuel Berenguel, Carlos Rodriguez, Antonio Visioli, Max Veronesi, and Julio Normey-Rico among other researchers.
