Abstract

The conditions for exciting of elastic oscillations in elements of a magnetic suspension design are found on the base of two-masses model. This model is used for fuzzy optimization of such magnetic suspension. Fuzzy optimization is carried out by means of the maximal region of attraction criterion (MRA-criterion). MRA-criterion admits a set of the optimal solutions in a class of the fuzzy logic functions-linear functions with saturation. A set of bounded control laws is found as a result of the fuzzy optimization. The undesirable effect of elastic oscillations exciting in elements of a magnetic suspension design is eliminated under found control
