The paper deals with automatic balancing of rotating systems during operation. After discussion of techniques' principles, balancing mechanisms designed on `AGH' University of Science and Technology are presented. After introduction into active balancing control algorithms, test results obtained during experiments are presented. The paper presents comparison between implementation process and results of experiments taken with two different control algorithms' implementation platforms: dSPACE rapid prototyping system and ALTERA FPGA system. The paper ends some conclusions about taken experiments and further works directions are presented.

The paper deals with autimatic balancing of rotating systems during operation. After discussion of existing techniques the novel concepts of balancing mechanisms are presented. The proposed method are easy to apply to various rotating devices, with no need of machine construction modification. Next basics of active balancing control algorithms are presented, and designed detection and correction algorithms are discussed. After descriptions of mechanisms, measurement and control algorithms, simulation and experimental results are presented. The paper ands some conclusions about presented active balancing mechanisms and further works directions are presented.

A theory of two-plane automatic balancing of rigid rotors is presented. For a rotor with two pairs of compensation balls or rollers the stability of compensation phasing is analysed by employing the method of direct separation of motion. The results are confirmed by computer simulation based on the complete equations of motion linearised in the vibrational co-ordinates.
