| Abstract |
The mathematical model of the inverter-fed induction motor drive system and the method of the offline
identification of its parameters are presented. The numerical method of static optimization has been applied
in parametric identification. Using experimental investigations, the influence of the excitation signals and the
conditions of supply and load on identified system parameters are analysed. Changes in the motor parameters are presented in the form of polynomial functions of the measurable motor quantities. An approximation of changes in motor parameters of the motor mathematical model with the use of polynomial functions has enabled the
adaptive control with open-loop adaptation on the basis of an off-line parameter identification. The experimental investigations were carried out on a laboratory model of inverter-fed induction motor drive. |
