Industrial Automatic Control Systems and Controllers Annotation << Back Synthesis of an Electric Drive Insensitive to Changes in Moment of Inertia V.I. Domanov, A.V. Domanov, D.G. Murzakov A control system for an asynchronous motor is considered according to a simplified dual-power scheme, which allows implementing the holding mode. A block diagram of the electric drive is drawn up and its stability is evaluated. It is shown that in transient modes there is an oscillatory component caused by the synchronization moment. A correction device is proposed that allows damping vibrations. The analysis of the control system when changing the moment of inertia of the electric drive. To reduce the sensitivity of the control system to variations of this parameter, it is proposed to use a special sensor that allows using the correcting circuit to maintain the dynamic characteristics of the system. The analysis of the influence of restrictions in the chain of the corrective link. The results can be used in the synthesis of similar systems with variations in the moment of inertia.
