Paper derives a procedure of identifying induction machine variable inductance values. Parameter identification is done from measurements during no-load direct start acceleration. Genetic algorithm is used for parameter identification. It is used to minimise least squares difference between calculated and measured data by selecting parameters of induction motor model. Variable inductance is identified...
The method of self-identification of permanent magnet synchronous motor inductances for efficient sensorless control has been proposed. The application of developed method allows us to improve the efficiency of motor. The method is based on automatic measurement of motor current time derivative for two positions of rotor. The algorithm of inductance estimation, which uses the obtained measurement...
The paper deals with identification of the equivalent circuit parameters of the induction motor. The identification has been done by comparison of measured torque and current characteristics and computed torque and current characteristics. Equivalent circuit of the induction motor has been used in form of the Γ-circuit. There is computed the dependency of the leakage inductance and the rotor resistance...
