Grey system based on flux estimation for vector control of asynchronous motors

In vector control of asynchronous motors, using voltage model for flux estimation ensures many advantages as regarding. Accuracy of estimation of stator fluxes is important in this model. Some inaccuracies occur due to uncertainty of parameters and measurement errors in the flux estimation. Grey systems theory provides simplistic methods for systems containing uncertainty. In this paper, the flux estimation is taken into account as a grey system and appropriate solution is introduced.
