【Abstract】 The vector control(VC) of matrix converter motor system(MCMS) was studied based on the control strategy of matrix converter and the VC of motor.Indirect method is the combination of the control of equivalent AC-DC-AC of MC and the VC of motor.The rectifier of the equivalent AC-DC-AC provides DC-bus voltage for the inverter that can be chosen from high,middle and low scope.The inverter uses hysteresis current control to implement VC.Direct method is the indirect method with DC-bus voltage in high scope.The effect of DC-bus voltage at high,middle and low scope on MCMS was studied.更多还原
