Presented project focuses on deriving the control algorithm capable of applying it on high speed drive. Introductory analysis allows to show advantages of field oriented control strategy over other control methods. Specific character of high frequency drive and chosen SFOC requests two estimators: for stator flux, and rotational speed. They are included in the design process. Derived algorithm is tested in the simulation. Afterwards, experiments were done with the induction drive. Lack of the high speed motor at the university laboratory, ends up with adjusting it on the conventional induction motor, supplied with 50Hz. Eventually, properly working control algorithm would be applied on the high frequency motor, available in Danfoss laboratory. Nevertheless, due to the time limitation, it could not be tested with the objective machine. Therefore, all the conclusions are drawn on basis of tests obtained with the conventional motor.
