This Bachelor's thesis covers the analysis of a hydraulic prototype drive for automatic handling and positioning of workpieces. In the first part of the thesis, the hydraulic and control components used are described in detail and three types of hydraulic valves are described: the conventional proportional, the direct-drive servo solenoid and the servo valves that are used for open-loop and closed-loop control of the position of the hydraulic cylinder piston rod. The main part of the thesis is the experimental analysis of the hydraulic control, in which we analyzed the basic characteristics of the system such as the speed profile at different operating conditions and position resolution. As part of the experiments, we also determined the optimal control parameters for the PID control of the position of the hydraulic cylinder. In the final part of the thesis is presented the concept of a real handling system and control for automatic cutting of pieces.
