Until 196s volutiony systms ws woking in plll with ntic Algoithm (A) sch. At this stg, volutiony pogmming ws dvlopd with th concpts of volution, slction nd muttion.

Ths high od modls cumbsom to hndl (Sivnndm nd Dp, 9). As sult, low od systm modlling cn b pfomd, which hlps in llviting computtionl complxity nd implmnttion difficultis involvd in th dsign of contolls nd compnstos fo high od systms. Futh, th dvlopmnt nd usg of mico contolls nd micopocssos in th dsign nd implmnttion of contol systm componnts hs incsd th impotnc of low od systm modling (Psd, ; 3; 3b). Thus, in this study, ntic Algoithm is usd indpndntly to high od systms nd suitbl low od systm is modlld (Sivnndm nd Dp, 9). Th vilbility of modn Pmnnt Mgnts (PM) with considbl ngy dnsity ld to th dvlopmnt of dc mchins with PM fild xcittion in th 195 s. Intoduction of PM to plc lctomgnts, which hv windings nd qui n xtnl lctic ngy souc, sultd in compct dc mchins (Islm t l., 11).

With th dvnt of switching pow tnsisto nd silicon-contolld ctifi dvics in lt pt of 195s, th plcmnt of th mchnicl commutto with n lctonic commutto in th fom of n invt ws chivd. Ths two dvlopmnts contibutd to th dvlopmnt of PM synchonous nd bushlss dc mchins (Islm t l., 11). Th mtu of th dc mchin nd not b on th oto if th mchnicl commutto is plcd by its lctonic vsion. Thfo, th mtu of th mchin cn b on th stto, nbling btt cooling nd llowing high voltgs to b chivd: significnt clnc spc is vilbl fo insultion in th stto. Th xcittion fild tht usd to b on th stto is tnsfd to th ot with th PM pols. Ths mchins nothing but n insid out dc mchin with th fild nd mtu intchngd fom th stto to oto nd oto to stto spctivly (Pilly nd Kishnn, 1989). In this study contins dsign of spd contoll fo pmnnt mgnt synchonous mchins using ntic lgoithm bsd low od modlling. Spd contoll dsign: Th dsign of th spdcontoll is impotnt fom th point of viw of impting dsid tnsint nd stdy stt chctistics to th spd-contolld PMSM div systms (Islm t l., 11). A popotionl-plus-intgl contoll is sufficint fo mny industil pplictions; hnc, it is considd in this wok. Slction of th gin nd tim constnts of such contoll (Tlbi t l., 7) by using th symmticoptimum pincipl is stightfowd if th d xis stto cunt is ssumd to b zo (Wllc, 1994). In th psnc of d xis stto cunt, th d nd q cunt chnnls coss-coupld nd th modl is non-lin, s sult of th toqu tm.
