Abstract :
Recently, the reliability and safety of electrical drives became very important, especially in critical applications, such as in automotive, aerospace and military industry. For such systems, it is desirable to detect and identify different kind of faults and, if possible, to continue operating after the fault occurs. After single open-phase fault is detected and identified, it is desirable to continue operating with reduced power. In this paper, modified direct torque control method for post-fault operation of permanent magnet synchronous motor is presented, without the need of changing the topology of power converter. In order to avoid negative torque operation, pre-firing angle is also introduced. The proposed method has been simulated and tested in Matlab/Simulink.
