N2 - The development of many modern products and processes is characterized by integration of digital control systems. Computer-aided methods for modeling, simulation and design are increasingly required; the reason are the increasing complexity and inter-relationship between the design of the processes and control systems. The aim of this diploma thesis was a Real- Time Simulation, in this case a Hardware in the Loop Simulation for hydraulic control of mining machines and visualisation of these simulation models. The developed system can be used in the implementation phase to emulate the behavior of the machines as a vehicle to test the control soft- and hardware. The simulation was designed with two different function-block oriented, graphical programming environments. After testing, a system with Matlab/Simulink and Real-Time Workshop implemented on a programmable logic control (PLC) was chosen. A complete real-time model was developed that is capable of simulating the essential properties of the real system (kinematics, dynamic behavior of the hydraulic system and the mechanical construction, further the cutting load force). The visualisation of the model is performed by displaying selected images from a rendered simulation video. The final system will be applied to test the automation software with the aim of improving the cutting accuracy, before the machine prototype is available.
