Effect of control in electrical drives on image registration supporting motion state estimation

In modern electrical drives, more and more smart algorithms are used to support the control. One of those algorithms is image registration, allowing, in a graphical way, to estimate the motion states from an image, registered from multiple samples of the phase currents and its time gradients. By searching for deformations in these images, such methods allow to take into account physical nonlinear phenomena such as magnetic cross-saturation, known to affect the motion state estimation of the rotor. In this paper, the image registration is illustrated on a DTC drive for a salient pole synchronous machine and the effect of control on the distribution of current sample points within the image is studied.
