| Abstract: | The article analyzes the relationship among the torque angle,the slip angular frequency of stator and rotor flux and the motor speed,and presents an improved Direct Torque Control algorithm.And then,the article calculates the referential voltage vector which could compensate torque and stator flux errors by using the increment of torque angle and the position of stator and rotor flux,and realizes the control over the voltage status of inverter on the basis of SVM technique,thus improving the performance of the system.At last,the article offers the simulation result,proving the rationality and validity of the algorithm. |
