Abstract
A method and a system for determining control parameters of a rotating electric machine, including: a two-phase imaginary reference frame module configured to construct two imaginary two-phase signals (x, x) based on a measurement of the mechanical position θof the axis of a rotor of the rotating machine received from a position sensor, an open-loop module configured to determine in open loop an estimate of the electrical speed, so-called the open-loop estimated electrical speed ω, using the imaginary two-phase signals, a phase-locked loop module configured to generate the actual electrical position θ of the rotating machine from the two imaginary two-phase signals (x, x) and using the open-loop estimated electrical speed ωreceived from the open-loop module.
