EN

An enhanced direct torque control (E-DTC) system of a synchronous reluctance motor (Syn-RM) is presented in this paper. The motor system is modelled by taking into account its non-linear behaviours such as iron losses and magnetic saturation. The proposed method consists of incorporating hysteresis DTC with a model reference adaptive system (MRAS) flux observer. This technique is applied in order to achieve good torque and flux ripples reduction, which ensure a smooth operation of the Syn-RM along all the speed range. Furthermore, the proposed method has simple design and implementation in the overall control system, and can avoid the drawbacks of conventional flux estimators. Simulation results show the effectiveness of the proposed method.

W artykule przedstawiono udoskonalony układ bezpośredniego sterowania momentem obrotowym (E-DTC) synchronicznego silnika reluktancyjnego (Syn-RM). Układ ruchu jest modelowany z uwzględnieniem jego nieliniowych zachowań, takich jak straty żelaza i nasycenie magnetyczne. Proponowana metoda polega na włączeniu histerezy DTC do wzorcowego obserwatora strumienia adaptacyjnego systemu odniesienia (MRAS). Technika ta jest stosowana w celu uzyskania dobrego momentu obrotowego i redukcji tętnień strumienia, które zapewniają płynną pracę Syn-RM w całym zakresie prędkości. Ponadto, zaproponowany sposób ma prostą konstrukcję i implementację w całym systemie sterowania i pozwala uniknąć wad konwencjonalnych estymatorów strumienia. Wyniki symulacji pokazują skuteczność proponowanej metody.
