This paper discusses the performance comparisons of a modified genetic algorithm, named as the semi-parallel operation genetic algorithm (SPOGA) and the conventional genetic algorithm (GA), in optimizing the I/O scale factors, membership functions, and rules of a hybrid-fuzzy controller. Singleton fuzzification is used as a fuzzifier with seven membership functions for both input and output of the controller, whilst center of average is used as a defuzzifier. A 21-bit-30-population is used in SPOGA for both I/O scales and for membership functions. Two control modes are applied in cascaded: position and speed. Both the simulation and practical experiment results show that fuzzy-logic parallel integral controller (FLIC) with SPOGA-optimized is better as compared to FLIC with GA-optimized and also the non-optimized FLIC, FLC, and PI in terms of performance and the reduction of the number of test runs for the optimization. © 2011 IEEE. date: 2011 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84857437011&doi=10.1109%2fPEDS.2011.6147223&partnerID=40&md5=6cbb5d87615c1378467ec37602c14120 id_number: 10.1109/PEDS.2011.6147223 full_text_status: none publication: Proceedings of the International Conference on Power Electronics and Drive Systems place_of_pub: Singapore pagerange: 51-56 refereed: TRUE isbn: 9781612849997 citation: Saad, N. and Wahyunggoro, O. and Ibrahim, T.
