Separating the influence of anisotropic properties of an induction motor during sensorless control at low angular velocity
Ihor KozakevychWe consider the construction of sensorless vector control using anisotropic properties of electric machines. Presented control system based on the use of high-frequency voltage injection that feeds the engine, and allows to perform compensation parasitic anisotropic. It is shown that determining the position of the axis anisotropy engine is possible by applying test vectors stator voltage to the engine or injecting a high-frequency voltage to the main feeding motor. The method of determining the provision for the allocation of current feedback signals using bandpass filters, eliminating direct sequence components by using filtering in the synchronous reference system using low-pass filter, and exposure compensation parasitic anizotropiy
