Development of a correction unit based on fuzzy logic for the control system of the load movement mechanism of an overhead crane

The purpose. Introduction into the bridge movement drive control system of a bridge support movement synchronization unit, developed in stages on the basis of fuzzy logic to eliminate bridge tilt arising as a result of the movement of a flexible suspension load along the bridge by a trolley. Methods. The objectives set in the study were achieved through the use of mathematical modeling in the Matlab Simulink environment and practical research. Results. The use of correction units, including those based on fuzzy logic, led to the elimination of the bridge tilt, reducing it to almost zero, and reducing the amplitude of elastic vibrations in the bridge truss to 45 percent. Conclusion. The use of control systems with correction units, including those based on fuzzy logic, allows eliminating the desynchronization of the speeds of movement of the bridge supports of the bridge crane, which reduces the load on the metal tructure of the crane, reduces the wear of the wheel flanges and crane tracks, and increases the reliability of the crane.
