Admittance control of an electro-hydraulic servo-drive

Abstract

The article describes the possibilities of electro-hydraulic servo-drive control in the admittance system. The principle of admittance control is presented and a method for implementing this kind of control for the servo drive controller has been proposed. Admittance method can be effective when there is a need for exerting precise force. This kind of measure extends the capabilities of control systems which uses only measurement of the displacement.
