Abstract
A method for controlling a permanent magnet synchronous electrical machine powered by a battery delivering a supply voltage to terminals of the battery, the method including: calculating an initial direct voltage component Vdc and an initial quadratic voltage component in a rotating reference; checking a saturation condition; calculating an angle α of a formula; generating voltages to be applied to the electrical machine if α varies negatively and Vdc is positive or if α varies positively and V dc is negative. The method for example can be applied in a control of synchronous electrical machines.
