Optimal gains tuning of PI-fuzzy controllers
Catarina Lucena, Luís Brito Palma, Alberto Cardoso, Paulo Sousa Gil · 2012
This paper presents a new methodology for tuning the gains of fuzzy proportional-integral controllers where the closed loop system performance is explicitly taken into account. The gains are found by solving a nonlinear constrained optimization problem considering the system's dynamics described by a nonlinear model, and including a set of constraints on gains, control actions and on the system outputs. Experimental results ilustrate the relevance of using the proposed tuning technique.
