A number of direct torque controllers for IPM motor drives have been developed in recent years. The main advantages of direct torque control over vector control include lesser parameter dependence and faster torque response. In this paper, a direct torque controller that uses a proportional + integral (PI) controller and reference flux vector calculator to determine the stator flux linkage vector...
The performance of direct torque control (DTC) interior permanent magnet (IPM) machines at low speed is poor due to a few reasons, namely limited accuracy of stator voltage acquisition and the presence of offset and drift components in the acquired signals. Due to factors such as forward voltage drop across devices in the three phase inverter and dead-time of switching devices, the voltage across...
This paper presents a new direct torque control (DTC) scheme based on space vector modulation (SVM) for interior permanent magnet synchronous machine (IPMSM) drives. The new scheme provides a variable option for the improvement of DTC controlled IPMSM. Closed-loop control of both torque and flux is developed with two proportional-integral (PI) controllers. The stator voltage is generator through SVM...
A modified direct torque control (DTC) scheme for the matrix converter fed interior permanent magnet synchronous machine (IPMSM) is proposed in this paper. Using the proposed method, besides the advantages of direct torque control strategy with matrix converter, it is possible to minimize the torque and flux ripples while maintaining constant switching frequency. In the proposed scheme, a modified...
A direct load angle control (DLAC) scheme of interior permanent magnet synchronous machine (IPMSM) is developed in this paper, which is based on load angle increment (Deltadelta) control without complex reference frame transformation. It features low torque and flux ripples and almost fixed switching frequency by means of space vector modulation (SVM). The theoretical analysis provides a guide to...
