Thesis (MScEng)--University of Stellenbosch, 2001. / ENGLISH ABSTRACT: The aim of this study is to critically evaluate the voltage injection position sensorless
control technique as applied to the reluctance synchronous machine (RSM) drive and
to implement the technique on a 5.5 kW RSM and a 110 kW RSM. The technique is
evaluated by using an accurate mathematical model of the RSM in a simulation
package, called Simuwin. The negative effects that cross-magnetisation and the
slotted air-gap have on the technique are intensively investigated. It was showed that
these effects can cause an error in the position estimation of up to 30°. The
TMS320F240 DSP was used as the controller for the RSM drives to implement the
position sensorless control technique. Measurements on both RSM drives confirm the
simulated results. / AFRIKAANSE OPSOMMING: Die doel van hierdie tesis is om die spannings-injeksie posisie sensorlose beheer
tegniek soos toegepas op die reluktansie sinchroon masjien (RSM) aandryfstelsel,
krities te evalueer en te implementeer op 'n 5.5 kW RSM en op 'n 110 kW RSM. Die
tegniek is geevalueer deur 'n akkurate wiskundige model van die RSM saam te stel en
die model te gebruik in 'n simulasie pakket, genaamd Simuwin. Daar is veral klem
gele op die negatiewe invloed wat kruis-magnetisering en 'n gegleufde lug-spleet op
die tegniek het. Dit is bewys dat hierdie eienskappe van die RSM 'n fout in die posisie
afskatting van tot 30° kan veroorsaak. Die TMS320F240 DSP is gebruik as beheerder
vir die RSM aandryfstelsels om sodoende posisie sensorlose beheer op altwee
masjiene toe te pas. Metings op albei stelsels bevestig die simulasies.
