Unlike PID controllers with fixed gains, a fuzzy PID controller is expressed in terms of fuzzy rules whose consequences employ analytical PID expressions. The PID gains are adaptive and the fuzzy PID controller has more flexibility and capability than conventional ones. Moreover, it can be easily used to develop a precise and fast control algorithm in an optimal design. An adaptive genetic algorithm is proposed to design the fuzzy PID controller. The centres of the triangular membership functions and the PID gains for all fuzzy control rules are selected as parameters to be determined. We also present a dynamic model of an AMB system for axial motion. The simulation results of this AMB system show that a fuzzy PID controller designed using the proposed AGA has good performance.<\/jats:p>","DOI":"10.1017\/s096012951300073x","type":"journal-article","created":{"date-parts":[[2014,9,5]],"date-time":"2014-09-05T00:08:51Z","timestamp":1409875731000},"source":"Crossref","is-referenced-by-count":4,"title":["Optimal fuzzy PID controller design for an active magnetic bearing system based on adaptive genetic algorithms"],"prefix":"10.1017","volume":"24","author":[{"given":"HUNG-CHENG","family":"CHEN","sequence":"first","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2014,9,4]]},"reference":[{"key":"S096012951300073X_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.conengprac.2005.12.002"},{"key":"S096012951300073X_ref8","doi-asserted-by":"publisher","DOI":"10.1109\/TMAG.2010.2042456"},{"key":"S096012951300073X_ref4","doi-asserted-by":"publisher","DOI":"10.1109\/TCST.2010.2048903"},{"key":"S096012951300073X_ref2","doi-asserted-by":"crossref","unstructured":"Chambers L.
