ADAPTIVE CONTROL SYSTEM FOR THE ROTATION MECHANISM OF LARGE-SIZED OBJECTS WITH A COMPUTER SUBSYSTEM FOR SYNCHRONIZING THE SPEEDS OF ASYNCHRONOUS MOTORS

The article is devoted to the method of developing an energy-efficient control system for a two-motor rotation mechanism OF large objects, where two asynchronous motors operate on the "master" – "slave" principle. The control unit is a synthesis of an ATMega 2560 microcontroller and a computer Simulink model of a two-motor asynchronous electric drive. The adaptability of the system is BASED ON the identification of the Electromechanical time constant of each engine, which, along with the use of precision angular displacement sensors, allows for accurate adjustment of the number of ROTATIONS of both engines.
