Design and Control of a Linear Rotary Electro-Hydraulic Servo Drive Unit

In this paper, a new solution for an electro-hydraulic servo drive is proposed, which consists of two drives: one with hydraulic cylinder and rotary motor. the proposed drive, linear actuator attached to horizontal base motor mounted on piston rod. Thus, output signal lifting lowering element suspended rope. The paper describes structure, kinematics, dynamics, control novel drive. A valve proportional are used flow Special attention paid construction actuators in unit. controller based PLC controller. measuring system uses laser displacement sensors encoder. results laboratory investigations discussed paper. contains all characteristics mechatronic device. main contribution study proposal architecture algorithm speed position when or loads.
