Synopsis:

Common linear theory of electric, hydraulic and electro-hydraulic servo-drives. Positional, speed and power servomechanisms structures, principles, device arrangement, transfer functions of regulators. Static and dynamic properties, dynamic compliance. Communication between control system and servo-drive, trajectory control of NC machines, position measuring systems. Mechanical gearings in servo-drives, optimization, rigidity, accuracy.
