Investigation of Electrohydraulic Drive Control System with the Haptic Joystick

Haptic Joystick in Admittance Control of Electrohydraulic Drive

In the paper the application of haptic joystick with magneto-rheological (MR) brake in control of electrohydraulic drive is presented. Two impedance and admittance control methods are shown. Basing on main equations describing electrohydraulic drive, the simulation model of an admittance control system is proposed. The results of chosen simulations are presented. Laboratory test stand is descri...

Simulation Investigations of Electrohydraulic Drive Controlled by Haptic Joystick∗∗

In the paper a control of electrohydraulic drive made by human operator which uses a special haptic joystick is presented. On the basis of main equations describing electrohydraulic drive, its simulation model is proposed. To this model a simplified model of human operator is added. The paper presents the system stability problem which can occur when in communication with operator, force feedba...

Electrohydraulic System Design and Control

This paper deals with the position control of a hydraulic actuator regulated by a proportional directional control valve. The control algorithms based on the proportional-derivative controller have been applied to a specially designed two-channel electro-hydraulic servo system, which has the capacity to experimentally simulate common circumstances of a typical fluid power circuit. The first sys...
