Direct torque control strategy for induction machine fed by space vector modulated matriz converter
Matrix converter(MC)is a hot spot will a series of advantages over the traditional converters.It is gradually being turned to application research with its more and more ripeness of theoretical study.A novel control strategy is put forward in this paper.It properly combines the space vector modulation of matrix converter with the direct torque control of induction machine through PI regulation of flux and torque，and improves the control performance of the system effectively, especially the property of electric magnetic torque at low speed.This PI regulator is simpler and has better robustness compared with deadbeat space vector modulation.First.Conventional principle of DTC and space vector modulation of matrix converter are described.Then the combination of the two is given in detail by PI regulator of flux and torque.Third,Simulation model is set up for the new kind of adjustable speed system.Finally,the simulation research is carried out according to three kinds of loads.Simulation results have verified the feasibifities and strong adaptability of the novel eontrol strategy,and it is worth further studying.
