HIGH POWER-EFFICIENT SENSORLESS CONTROL OF SYNCHRONOUS RELUCTANCE MOTOR Mynář, Zbyněk ; Talla,, Jakub (referee) ; Lettl, Jiří (referee) ; Václavek, Pavel (advisor) Synchronní reluktanční motory se pro svou relativně vysokou účinnost, robustnost a nízkou cenu stávají stále populárnější alternativou velmi rozšířených asynchronních motorů. Snaha o využití výhodných vlastností bezsnímačového řízení, a dosažení co nejvyšší účinnost jejich provozu, je však komplikována jejich výraznou nelinearitou způsobenou saturací magnetického obvodu. Úvod této práce je věnován popisu matematicko-fyzikálního modelu SynRM a přehledu existujících moderních algoritmů výkonově-optimálního bezsnímačového řízení. Jádrem práce je pak představení estimátoru stavů a parameterů SynRM postaveného na novém přístupu k měření a využití fázových reluktancí. Klíčovými prvky algoritmu jsou nová metodologie měření fázových reluktancí, spínací PWM schéma jež umožňuje snížit spínací ztráty a měřit fázové reluktance od nulových otáček, a nakonec integrace těchto měření s matematickým modelem SynRM s pomocí rozšířeného Kalmánova filtru. Experimentální část práce pak diskutuje výsledky reálných měření s navrženým algoritmem a vybranými současnými algoritmy. Detailed record
