Optimal feedforward compensators for systems with right-half plane zeros

Rodríguez, Carlos ; Guzmán, José Luis ; Berenguel, Manuel and Hägglund, Tore LU (2014) In Journal of Process Control 24(4). p.368-374
Abstract
Feedforward from measurable disturbances is a powerful complement to feedback control to improve disturbance rejection capability. Recent works have remarked the necessity of a design strategy for those cases where the ideal feedforward controller is not realizable. In this paper, a simple shaping design procedure is presented together with straightforward rules to obtain optimal feedforward controllers for the case when the ideal compensator is not realizable due to right-half plane zeros in the process dynamics. Finally, some simulations and a robustness analysis demonstrate the benefits of the proposed tuning rules.
