W pracy dokonano analizy wpływu złożoności przybliżonego modelu odcinkami afinicznego służącego do syntezy regulatora sektorami afinicznego na własności układu sterowania w sytuacji, gdy sterowany obiekt jest nieliniowy. Zaproponowano metodę wyznaczania przybliżonego modelu odcinkami afinicznego, umożliwiającego optymalny dobór węzłów, minimalizującego odchylenie pomiędzy funkcją nieliniową i jej przybliżeniem. Rozważania przeprowadzono na podstawie dyskretnego modelu pojazdu na nieliniowym wzgórzu.

The paper presents analysis of the impact of the complexity of the approximate piece-wise affine (PWA) model used to compute PWA regulator on the eon troI system properties with nonlinear plant. The method for de termin ing the approximate piece-wise affine model is proposed. The method allows the optimal nodes selection and minimize the deviation between the nonlinear function and its piece-wise affine approximation. Considerations are based on the car on nonlinear hill discrete-time model. (Effeet of the partitions of approximate seeant pieee-wise affine model on eon troI quality for non-lineer, state-dependent system).
