Abstract :
The article describes the results of research and development of observer torque on the shaft and the state variables of asynchronous motors with double squirrel cage rotors or deep-slot-type rotors. Observers of the state variables are used for constructing the sensorless control system of asynchronous electric. To estimate the load torque mathematical description based on the Luenberger observer complete order is used. The passive filter of disturbances compensation is proposed as the developed load torque observer. The research methods include automatic control and electrical machines theory, and operational calculus methods. The MatLab/Simulink software applications were used. The paper presents the graphical results of numerical simulation and shows the efficiency of the developed algorithms and techniques.
