Method of control of an alternating current electric motor, computes voltage vector angular offset arising from delay with slow processor performing control computations

摘要

The method of control takes into account processor computation time. The tension applied to the motor is calculated for an angle =H=n which is equal to the angle =H of the rotor at the start of the computation plus the phase offset corresponding to the displacement of the rotor during time taken for the processor to compute the required voltage.
