Sažetak
This paper reports the design and control of a 50 kN hydraulic press which is made for experimental verification of control algorithms as well as for educational purposes. The press contains a servo-solenoid pressure control valve for regulating the pressure in the cylinder chamber and thus the force of hydraulic press. The system is equipped with a pressure sensor installed in the cylinder chamber for indirectly measuring the pressing force. At the considered press it is also possible to measure position of the upper plate by using a micro-pulse linear transducer. This created conditions for the realization of a position/force hybrid control algorithm. The control algorithms and monitoring process are implemented on a real-time hardware board. They are programmed in Matlab/Simulink environment using Real-Time Workshop tool for generating the C code and building an executive program. Based on the experimental results it can be concluded that electrically actuated control components supported by appropriate computer programs enable the realization of improved characteristics of systems required in modern industrial plants.
