| Abstract This paper presents the design and implementation of fuzzy logic controller (FLC) to improve the efficiency of a separately excited dc motor .The improvement of motor efficiency is achieved by controlling both armature voltage and field voltage simultaneously which are decided by the FLC. DC-DC converters (chopper Buck) are utilized to control armature voltage and field voltage. Design and MATLAB simulation are presented together with implementation of fuzzy logic controller using microcontroller type(MC9S12DP256B).The results show that the efficiency of the DC motoris clearly increased in light and medium load torques in comparison to the armature fuzzy speed controller. Key words: speed control of DC motors, fuzzy control, and efficiency enhancement. | ||
