摘要
This paper presents a simple dynamic overmodulation method to obtain a quick dynamic torque response in DTC hysterisis-based system. The fastest dynamic torque response is achieved through the proposed dynamic overmodulation method by applying only single appropriate voltage vector that produces the largest tangential flux component during transient condition. In this way, the flux error status produced from the flux hysterisis comparator is modified before it is being fed into the look-up table in order to perform the dynamic overmodulation mode. The effectiveness of the proposed dynamic overmodulation to obtain the fastest torque response is described with some simulation results given.
