| Abstract | ||||
| In this paper a fuzzy logic control of a field oriented ac motor drive using a dynamic drive model is investigated and simulation studies are performed with the matlab program. A mathematical model of the induction motor operating at constant speed and supplied from a symmetrical three phase supply is given. The dynamic model is simplified based on the reference frame theory and linearization technique. The fuzzy logic controller for speed loop is presented. The input variables to the controller are normalized by certain gain factors estimated by trial and error. The membership functions for the linguistic variables are represented by a symmetrical triangular shapes causing more crowding near the origin and precision control near the steady state operating point. The effectiveness of the proposed fuzzy controller is investigated and compared with an adjusted PI controller. The simulation and practical results are presented. | ||||
