| Abstract: | The effect of the voltage vectors on the amplitude of stator flux and torque angle in the permanent magnet synchronous motor(PMSM) direct torque control(DTC) system was studied.Torque dynamic behavior due to the application of the voltage vector was analyzed.The voltage vector selection strategy was given.An easy way to increase useful voltage vectors was proposed and an optimal switching table was given to suppress torque ripple.Simulation result confirms the theory analysis. |
