Digital Control System of Two-Motor Ac Electrical Drive Built by Principles of Harland

In the paper, optimization of scalar control system of two-motor electrical ac drive with individual regulators of speed is investigated. Structural scheme of the drive is constructed via electromagnetic process agreement taking into account elasticitic shaft. The expressions for the optimal parameters of digital regulators for stator currents of the motors and speed of the drive are given. Modelling results obtained on the computer are given. The considered system of ac drive provides optimal dynamic character as well as automatic distribution of loading between the motors.
