Modelling and simulation of an electro-hydraulic mining manipulator

A method for modelling an electrohydraulic system is presented in this paper. Without directly using the conventional linear models, accurate models for the electrohydraulic components have been constructed using the characterisation data provided by manufacturers and measurements obtained in the laboratory with a custom built electrohydraulic manipulator. A commonly available general-purpose simulation package, Simulink, has been used to solve the nonlinear differential equations.
