The system to the position - and the speed in the case of a permanent magnet - rotor of an electric machine

摘要

Device for the determination of the electric drive - position (φ_em) and - speed (ω_em) a permanent magnet - rotor of an electrical brushless linearly - or - rotary machine in particular for a drive circuit as a rule, suitable for use in the system according to any one of the preceding claims, comprising the following functional components:a) with a circuit - and / or programmed machines - modeling module (9), comprising:aa) initially - interfaces (10, 11, 12) for in a rotor, d, q - coordinate system transformed machines - along - and - transverse vector components (i_d, i_q; u_d, u_q) from the stator - current (i₁, i₂) and a predetermined voltage as well as for the determined speed (ω_em),ab) and at least two output - interfaces (13, 14) for in the d, q - coordinate system transformed vector components (δu_d, Δu_q) an internally calculated voltage deviation,b) with a circuit - and / or program means for outputting the position and / or speed of the linkage means 17-20 could be realized according to the controller (6), which is connected:ba) on the input side with the at least two output section points (13, 14) of the modeling module (9)bb), and on the output side with the speed - initially - interface (10) of the modeling module (9),characterized in that..
