Abstract


A kind of Direct Torque Control System based on ADRC and SVPWM for asynchronous motor is designed. For the purpose of restraining the ripple of electro-magnetic torque and flux linkage, SVPWM is used in the system as an improvement. At the same time, PI controller is replaced by ADRC controller to overcome its disadvantages. Simulation of SVM-DTC system based on ADRC is realized. Simulation results have shown that the system can restrain the ripple of electro-magnetic torque and flux linkage effectively. It also has a good resistance to disturbance caused by the change of load torque.
