Comparison of Conventional and Fuzzy-Control of Non-Linear Systems
H. Knappe · 1994
The results of conventional control theory are not really satisfactory in cases of non-linear systems of high order with uncertainties in parameter and structure. This is mainly due to the necessary reduction in order and simplification of the system. A fuzzy controller, on the other hand is not based on mathematical modells. Consequently, it is especially suitable for technical non-linear processes for which verbal control strategies are known. This paper presents the speed and position control of an elastic two-mass-system with slack. A fuzzy controller is compared to the conventional theory. A systematical fuzzy controller design as well as the robustness of the system concerning uncertainties in parameter and structure are researched.
