The stable operation regions are the important issues for direct torque control (DTC) system of permanent magnet synchronous motor (PMSM). The influences of the parameters, such as voltage, current, flux linkage and load angle, on the system operation are investigated through the analysis model presented in this paper. The analysis results show that the parameters must be properly regulated within...
In this paper, a pure torque loop control method without flux linkage observer and a modified double closed loop control method with a couple of derived simple equations for the control of the stator flux linkage amplitude were proposed for direct torque control (DTC) of brushless DC motor (BLDCM), using a 2-phase conduction mode. The objectives of the novel control strategies are trying to simplify...
This paper presents an improved direct torque control (DTC) method for permanent magnet synchronous motors. The proposed DTC method generates the diver signal with SVPWM for the fixed switching frequency and low torque ripple relative to conventional hysteresis controllers. Different with the popular SVM-DTC, the proposed method obtains amplitude and angle of reference voltage vector directly by the...
