Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a free-run pull-in method capable of pulling a permanent magnet rotor synchronous motor into speed-controlled driving suitably even while it is in a free-run rotation. SOLUTION: A δ-axis current command and a γ-axis current command are set to prescribed values respectively, and a δ-axis voltage command and a γ-axis voltage command, corresponding to the set δ-axis current command and γ-axis current command respectively, are generated to supply current to a synchronous motor. The currents of at least two phases of the synchronous motor undergo γ-δ conversion, based on γ-δ coordinate-axis position information at the immediately previous period of sampling to determine a γ-axis current detected value and a δ-axis current detected value.  Based on a predetermined γ-axis and δ-axis current-voltage equation, a γ-axis current estimated value and a δ-axis current estimated value as well as a y-axis induction voltage estimated value and a δ-axis induction voltage estimated value are determined, to estimate the symbol of angular velocity, an angle velocity estimated value, and the position of γ-axis. Thus, the vector control for ordinary operation is started based on the angular velocity and the position information of a rotor obtained by free-run pull-in processing.
