The problems of analysis, modelling and simulation of drive systems are solved on Institute of Mechanics of Solids for over 20 years. During that time period not only the solved problems changed but also the drive systems themselves and mainly the requirements on what to solve and how to do it. Today the drive systems is considered mainly as interactive systems containing a range of subsystems with different physical nature: mechanical (the basic ones), electrical or hydraulic, pneumatics and also electronic (control ones). Models of those complex systems can then be characterized as so called "purpose build and partially structured". The models of those partial subsystems have its typical signs and properties, which can often essentially influence the dynamic properties and global system models behaviour. The aim is to keep so called functional model purpose - in comparison with the real system, which does not necessarily mean that the model must contain all the function and signs. By contrast we suppose that those function have its carrier, which in limit case can be represented by black box. The control of such systems the more and more often require use of intelligent control algorithms, based for example on genetic algorithms or artificial neural network.
