Improving performance of a hydraulic press with real-time nonlinear control
This paper focuses on the design and robust nonlinear controller synthesis based on the backstepping approach for force real-time control of a 50-kN hydraulic press. The main feature of the test system is its open hardware structure and easy programmability using different control devices and appropriate control strategies. A nonlinear dynamic model of the hydraulic system interacting with environment has been developed. The press contains a servo-solenoid pressure- control valve for regulating the pressure in the cylinder chamber. The press is equipped with a pressure transducer installed in the cylinder chamber for indirectly measuring the pressing force as well as with a load cell inserted below the piston rod and environment for directly measuring the applied force. On the press is also possible to measure the position of the upper plate by using a micro-pulse linear transducer. The experimental results illustrate that the proposed control technique enables a better tracking performance compared to the conventional PI controllers and guarantees the convergence of the tracking error.
