Closed-loop tuning rules for feedforward compensator gains

Veronesi, Max; Guzman, Josè Luis; Visioli, Antonio and Hägglund, Tore LU (2017) 20th IFAC World Congress, 2017 In IFAC-PapersOnLine 50(1). p.7523-7528
Abstract
This paper presents new simple tuning rules for the gain in feedforward compensators. When the ideal feedforward controller is not possible to implement, a negative effect is introduced in the closed-loop response. So, the closed-loop transfer function from the disturbance to the error is analyzed and tuning rules for the feedforward gain are proposed. Two feedforward structures are used, a lead-lag compensator and a static controller. First, the feedforward gain is tuned to reduce the overshoot in the response for both compensator structures. Afterwards, a second tuning rule for the feedforward gain is derived to minimize the integrated absolute error. Finally, the different tuning rules are evaluated through simulations and compared with... (More)
