Abstract For the conventional direct torque control torque and flux control of the phenomenon, there is a large deviation, from the analysis of the mathematical model of permanent magnet synchronous motor(PMSM),effective to estimate the stator flux and torque on the basis of the direct torque control strategy based on space vector pulse width modulation(SVM); Meanwhile, proportional resonant controller(PR) can realize no static error adjustment tracking when the input signal is AC signal in the stationary coordinate system, Introduction into the control system can overcome the deficiency of the PI. The final design of a control system based on dual-PR controller PMSM-SVM-DTC. Proved through the analysis of simulation compared with the conventional DTC, the program can maintain a fast dynamic response characteristics as well as good robustness, but also effectively reduces the flux and torque ripple, and further experiments to verify the feasibility and effectiveness of the program, with engineering applications.
