Abstract |
In recent years, switched reluctance motors have occupied a wide spectrum of applications for variable speed drives, because of their simplicity and versatility of control. This paper introduces an attempt to use fuzzy logic to model and control a switched reluctance motor drive. Fuzzy based modelling does not require an accurate mathematical model which is very difficult to obtain from a switched reluctance motor (SRM) because of its inherit nonlinearities. An application of fuzzy sets to the SRM drive control was also applied to the speed loop, replacing the conventional PI controller. The results of applying the fuzzy logic controller (FLC) to SRM were compared to those obtained by the application of a conventional PI system. Compared to a PI control the fuzzy logic control provided a better response in terms of accuracy, and insensitivity to changes in operating conditions. The fuzzy controller shows robustness over a wide range of operations. |
