The paper deals with development of a mathematical model of valves of a hydraulic system. A three tank laboratory model (Amira DTS200) was investigated and characteristics of its valves were measured and a process of creating a mathematical model of the valves is described in detail. Although the three tank system is a classical modeling task this paper focuses on nonlinearities which are present in real system and other differences between ideal mathematical model and real-time system. The valves contain hysteresis and other nonlinearities. Despite the fact that all valves the system is equipped with are of the same type, big differences were observed between their characteristics. The approach to modeling of the system is not restricted to the particular system but can be used for many real-time hydraulic systems.
