摘要：A process is disclosed for controlling the switching-off process of the branchesof a reluctance engine whose stator is provided with windings to which are transmittedcurrent pulses calculated as a function of angular position and speed of rotation of therotor according to a predetermined algorithm. The excited branch is switched off when aswitching-off angle (VP) is reached after a zero crossing (vo) reference angle. Two rangesof operation called 'chop' range and blocked voltage range must be differentiated. Theswitching-off angle (VP) for both ranges of operation of the reluctance engine is
calculated according to the same algorithm and is set by a regulator. In the lower speedof rotation range, the 'chop' range, a pulse width modulated voltage is applied to theconductive branch and in the upper range, the blocked voltage range, a constant voltageis applied. In both ranges, the switching-off angle is calculated from engine parametersand actual operation values to maximise torque yield and to trigger the switching-offprocess by converting said values into a switching-off pulse that switches off theconductive branch.
