ABSTRACT:
This deadbeat control method of controlling an asynchronous rotary electrical machine consists of:a) a step of establishing a set point current that is adapted to achieve at the end of the interval T both the mechanical force set point and a set point magnetic flux and is established on the basis of a relationship between the set point current, the set point magnetic flux and initial current and magnetic flux values at the beginning of the interval T; andb) a step of calculating an average control vector to be applied continuously during the interval T to obtain at the end of the interval T a current equal to the set point current established during the step a).
