Industrial Automatic Control Systems and Controllers Annotation << Back Research of Identification of Elements of System of the Multi-motor Electric Drive of a Slip of Shipbuilding Plant V.I. Domanov, A.V. Domanov, S.V. Gavrilova The analysis of the existing electrical equipment slip and its drawbacks are noted. In order to modernize, the possibility of using an asynchronous engine with two sets of stator windings to create a multi-motor electric slip-type ship-raising complex is substantiated. The proposed scheme of the system agreed on the speed of rotation of the engines. In the process, there are differences in the parameters between the individual electric drives, which leads to the appearance of additional errors. It was proposed to identify the main parameters and eliminate the errors with the help of correction circuits. A model of the electric drive was compiled based on the description of the elements of the control system. Also an analysis was made of the possibility of correcting static and dynamic errors in the mismatch of the parameters of the electric drives. A transient graph is obtained when the error correction circuit is turned on. Taking into account the random nature of the occurrence of the considered error, the effect of the difference in parameters on the magnitude of the signal dispersion is determined.
