This article presents an optimization-based method to tuning Proportional-Integral (PI) controllers for systems subject to actuator saturation and constraints on the controlled variable. The theory of invariant sets is used to treat constraints and a polytopic model is adopted to account for actuator saturation. For the numerical validation of the method, four examples are presented. The results show that the method can establish a tuning that does not violate any constraint.

PL

W artykule przedstawiono opartą na optymalizacji metodę strojenia regulatorów proporcjonalno-całkujących (PI) dla układów podlegających nasyceniu elementów wykonawczych i ograniczeniom na regulowaną zmienną. Teoria zbiorów niezmienniczych jest wykorzystywana do leczenia ograniczen, a model politopowy jest przyjmowany w celu uwzględnienia nasycenia elementu wykonawczego. W celu numerycznej walidacji metody przedstawiono cztery przykłady. Wyniki pokazują, ze metoda może ustanowić strojenie, które nie narusza żadnego ograniczenia.
