dc.description.abstractThis thesis is centered around the commissioning, testing, modeling and experimental validation of a pump-controlled hydraulic actuator capable of controlling large inertia loads. Prior to the thesis an experimental test bed had been constructed mechanically and hydraulically, and placed at the University. The primary focus of this thesis has been finalizing the experimental test bed in terms of building the electrical setup, placing instrumentation, developing software, tuning the electrical motors, followed by commissioning and testing of the experimental system. At the time of completing the thesis, the system has been completed, successfully commissioned and tested with position feedback-control. A numerical simulation model has been developed and validated against experimental data, with good agreement between the developed model and the experimental systems behavior. The real systems energy consumption has been measured and compared to that of a conventional servo valve controlled system, and shown to be significantly less while still capable of controlling large inertia loads with high accuracy. Using position feedback control the pump-controlled system achieved a settling time of 2.3 seconds and 0.18mmsteady state accuracy for the maximum effective load of 10 000 kg.en_US
