Abstract
The problem solution of a fuzzy logic controller (FLC) synthesis for a combined vibration isolation system with an electromagnetic motor is considered. An analysis of the passive system characteristics is carried out and its key disadvantages, the presence of a pronounced resonance peak and the ineffectiveness of vibration isolation in the low-frequency range, are identified on the basis of a mathematical model of a vibration-protective platform on elastic suspensions. The structure of the FLC is proposed, a system of production rules is drawn up, a parametric synthesis of the FLC is carried out by finding the optimal centers location of the accessory functions terms for input and output quantities. Using mathematical modeling in the MATLAB Simulink software package, the advantages of a synthesized combined system over a passive installation are demonstrated.
