Device of identification of parameters of the three-phase asynchronous motor

Abstract

The analysis methods to identify the parameters of automatic systems and electric motors is performed. It is shown that for the identification of the parameters of three-phase induction motor is advisable to use a continuous gradient method for finding the minimum of a function. A mathematical model of the system of identification of parameters of the induction motor is given. Developed the functional diagram of the device identification. Shown that the device identification can be realized using simple components such as multiplier, adders and integrators.
