Dynamic properties of the subordinated control system of the electric engine with a proportional velocity controller

摘要

The results of the standard optimized system analysis of the thyristor transformer-drive with proportional velocity regulator are listed. It's shown that the simplification of the transfer function structure of the direct current engine (DCE), where the mechanical moment on the spindle of the engine is substituted by its electromagnetic moment (this simplification is used in the modern automatic control theory), leads to the disturbance of the DCE's basic physical characteristics in the SAR system as damhing element, with viscosity friction, the rewith qualitative modifications of the SAR's electric drive dynamic characteristics take place, which appreciably have an influence upon the choice of the corrective devices and regulator's parameters.
