| Abstract |
The tolerance-band (hysteresis) current control method is widely used in the control of high dynamic speed-controlled drives fed from voltage-source PWM-inverters. In this paper a new current controller, which completely removes the problems associated with this traditional method, will be presented. A comparison of the new controller with the hysteresis current controller shows a considerable reduction of the switching frequency of the inverter while eliminating the overshoot in the current deviation. Analytical and experimental investigations on a current regulated induction motor drive confirm the predicted advantages of the new current controller. |
