Abstract
The article reports on the design and control of a 50-kN hydraulic press that was made for educational purposes as well as for an experimental verification of control algorithms. The press contains a servo-solenoid pressure-control valve for regulating the pressure in the cylinder chamber and thus the force of the hydraulic press. The press is equipped with a pressure sensor installed in the cylinder chamber for indirectly measuring the pressing force. On the press it is also possible to measure the position of the upper plate by using a micro-pulse linear transducer, which creates a precondition for the realization of a hybrid force/position- control algorithm. The control algorithms and monitoring process are implemented on a real-time hardware board. They are pro- grammed in the Matlab/Simulink program using the Real-Time Workshop tool for generating the C code and building an executive program. The article also shows an industrial solution for hydraulic press control using a programmable logic controller (PLC) as a control device. Based on the experimental results, it can be concluded that electrically actuated control components supported by the appropriate computer programs make it possi- ble to improve the characteristics of the hydraulic systems required in modern industrial plants.
