A method for direct torque control based on inverter basic voltage vector prediction |
| abstract |
The invention discloses a method for predicting direct torque control based on an inverter basic voltage vector. Six basic voltage vector predictive controls are selected for stator flux linkage amplitude and torque value; two basic voltage vectors are removed, and sector position signal judgment is added to select four basic voltage vector predictive controls; The torque control signal is used to select four basic voltage vectors to improve the predictive control through the stator flux linkage amplitude and torque value at the next moment; compare the obtained six basic voltage vectors, four basic voltage vectors and four basic voltage vectors to improve the The objective function value, the torque root mean square error and the stator flux root mean square error are obtained, and the torque prediction control is carried out. The present invention can reduce the torque ripple and the stator flux link ripple, and has the further advantage of reducing the number of switching tables. |
