Course detail
Electrical Servodrives
FSI-RES Acad. year: 2018/2019 Winter semester
The subject familiarises students with the basic problems of electrical servodrives and their role in motion control of production machines and appliances. The basic demands on static and dynamic properties of servos are defined, the basic components of electrical servosystems (DC,electronically commutated DC, synchronous, asynchronous and linear machines, power converters, sensors and controllers) are explained, the design-methods of feedback systems (position-loop, speed-loop, current-loop, position control with subordinate speed and current control, dynamic stiffness of a position-loop, communication between a numerical control system and servodrives) are treated and the interaction of load-inertia of servomechanisms is described.
