Permanent magnet synchronous motor (PMSM) is a strongly coupled nonlinear system. In this paper, the speed control of PMSM with the direct torque control (DTC) scheme and SVPWM is studied, where the fractional order calculus theory is used to design the fractional order PIλDμ controller. Simulation results show that the proposed fractional order PID control system has better dynamic performance and...
In recent years direct torque control (DTC) has become an alternative to the well known vector control especially for permanent magnet synchronous motor (PMSM). But it presents a problem of field linkage and torque ripple. In order to solve this problem the conventional DTC is combined with space vector pulse width modulation (SVPWM). This control theory has achieved great success in the control of...
This paper proposes a simple method direct torque control (DTC) based on space vector pulse width modulation (SVPWM) of surface-mounted permanent-magnet synchronous motors (SPMSM). The proposed DTC method calculates the optimized voltage vector using the motor parameters and the analysis of the relationship between the stator flux, torque, and stator voltage to calculate the optimized voltage vector...
A direct torque control strategy for dual three-phase permanent magnet synchronous motors is presented in this paper. The motor has two sets of three-phase stator windings spatially phase shifted by 30 electrical degrees. In order to reduce the harmonic current in stator windings which has no contribution to torque production, torque and flux are controlled based on regulators and three-phase decomposition...
The continuous improvement of social practical production demands modern motor controlling technology. PMSM has been widely applied to those occasions of high performance because of its excellent performance. However, there are large flux linkage and torque ripples and inconstant switching frequency in the conventional DTC. To solve these problems, PMSM DTC using SVPWM based on the subdivision of...
To solve the problems of torque ripple and inconstant switch frequency of inverter in the conventional direct torque control (DTC) for permanent magnet synchronous motor (PMSM) drive, a novel DTC method using space vector pulse width modulation (SVM) is proposed based on analysis of PMSM mathematical model. In this novel DTC system of PMSM , traditional torque hysteresis controller and flux hysteresis...
Direct torque control (DTC) can produce quick and robust response, but it has the problems of large torque ripples and inconstant inverter switching frequency. This paper introduces a modified direct torque control based on the space vector pulse width modulation (SVPWM) for interior permanent magnet synchronous motor (IPMSM) drive without a speed sensor. Two PI controllers regulate the flux and torque...
