"Mining production in underground spaces will be in the future realized by intelligent robotic systems without human presence. The control of these processes will be based on application of autonomous cooperative units that can be put together to manage the production goals. As the mining production is connectes to natural raw materials deposits, where the process environment models and activities cannot be fully determined, the human supervision will be necessary. Classical process control, with the external system description of the dynamic behavior will be changed by the use of holonic systems that can be will suited to responsive manufacturing settings, where the manufacturing processes regularly changes. Similarly for the process visualization the classical methods - SCADA (Supervisory Control and Data Acquisition) systems will be changed by more sophisticated technology given by tools of virtual reality. Models used in process control are based on the state representation of systems, caused by the necessity to obtain more information to understand and describe the dynamics of complex system in the control process. State space model that represents the dynamic properties of the system and the behavior of system in the state space is represented by the state trajectory (given by values of state variables in the observed time period). The problem occurs in many cases that the state variables do not have the physical dimensions and we are not able to measure them. The Virtual Reality tools provide the possibility for effective visualization of such a virtual and complex systems description in special artificial space."@en . . "1314-2704" . .
