Abstract
Starting with a systematic of hydrostatic drives the paper shows which kinds of control are used today and how they can be divided to find a good analytical way of describing open and closed loops. Open loops can be distinguished by primary and secondary control. Closed loops are divided into force or torque control, speed control and position or angle control. Typical performances of linear and rotary drives are discussed using state-of-the-art controllers. The paper finishes with the controls necessary for the supply of hydrostatic drives, which is mainly a pressure control but can also be a flow or power control.
