A parameter sensitivity analysis method is applied to an investigation of the importance of the identification accuracy of the parameter values describing the steady-state and dynamic behavior of three commonly used fluid power circuit components, i.e., single-stage pressure relief, reducing, and two-way flow control valves. The component models are verified; these semi-empirical models take into account the most important continuous and discontinuous nonlinearities.
