Operation Analysis of the Induction Motor Coordinated Rotation Control System

Operation analysis and synthesis of the coordinated rotation system based on the two-speed induction motors (IM) with cage rotors presented. The circuit uses a transistor voltage controller to maintain the speed of IM. The second group of IM windings is used for parametrical synchronization, while transistor controller is used to compensate for the residual error. Transfer functions of the original and the corrected system are obtained. The calculation of the corrective link is presented for the system tuned on the technical optimum. The system's transfer function sensitivity to variations of different links is determined. The systems were simulated and transition processes were obtained for different operating modes.
