Dear all, I would like to measure the flux of an induction machine using its terminal voltages and currents. The block diagram that should be implemented is as the attached picture. In the block diagram of the figure the lines represent space vectors, with their two components. The superscript s denotes that the space vector is referred to a static reference frame (alpha-beta axis).The gain (1/jws ) is equal to shifting the input value by -90 degrees. It seems like that the real and imaginary of the input voltage and current should be subtracted separately. If this is the case, how can I merge the them into one signal after subtraction.

Second, on what basis the integrator should be reset?

Third, how 1/j gain can be implemented?

Thanks,

Hassan
