Abstract

PURPOSE: To accomplish accurate magnetic flux detection over a broad frequency range including low frequency through compensation by inputting the output to a vector rotary device after applied voltage and current are inputted to an integrator and LPF.
CONSTITUTION: (v1 - R1 × i1) is calculated axially with respect to the axis d and the axis q based on applied voltage v1 and applied current i1 and inputted into integrators 1 and 3. Each output undergoes a negative feedback through LPFs 2 and 4 to perform the P-I action for removal of DC component. The output of a compensation 5 to which an angular velocity ω1 for compensation of the P-I action is inputted and the output of the respective integrators are inputted into a vector rotary device 6 which outputs a flux vector component irrelevent to the input frequency through computation of the equation 5. The output is passed through a rotor flux operator 7 and vector analyzer 8 to determine the direction and the magnitude of gap flux vector.
