摘要：

In the paper a new way of DTC control method analysis to explain flux and current distortion at a low speed of motor operation is discussed. As a result, a new DTC-5 algorithm is proposed. It is important that the DTC-5 algorithm uses the same switching table as the DTC method. The modified DTC algorithms are free from the disadvantages of the conventional DTC method i.e. hexagonal flux and strongly deformed current at a low speed range. The dynamical properties of the new algorithms are similar to the conventional DTC method. The correctness of the proposed methods has been confirmed by laboratory investigations.
