This paper presents the new laboratory test rig of the vertical axis flexible shaft supported by two active magnetic bearings. Behind the motivation of establishing this setup is the control of vibration modes of the flexible rotor - shaft assembly, while the rotational speed varies and the unbalanced mass on the whirling disc is introduced to the system. The proposed model is aimed to simulate real operation conditions of the rotating machinery with an applied external load, with a variable structure caused by a change of material properties of the rotor - shaft assembly, or due to a fault of some elements coupled with the rotor.

The paper presents an approach to modeling programs for reconfigurable logic controllers using Unified Modeling Language and Petri net notations. The proposed design method attempts to combine the advantages of graphical notation (readability, convenience, intuitiveness) with the benefits of text specification languages (precision, versatility) and sophisticated model verification tools. The UML model and Petri net model are transformed separately into effective programs in Hardware Description Languages (Verilog, VHDL). Moreover, the Petri net model (created based on UML model) can be used for analysis and verification of the designed system. The obtained HDL specifications can be simulated, synthesized and implemented in modern reconfigurable Field Programmable Gate Array devices. A practical example illustrating the benefits of the proposed method is also presented.
