Increasing the Damping Capacity of Crane Electric Drive Systems When Moving Cargo with a Flexible Suspension

Mechanical vibrations that occur in industrial production mechanisms have a negative impact on both the electrical part and the mechanical part of the electric drive, which is a system of connected masses that move at different speeds, both translational and rotational. Bridge cranes contain mechanisms that are influenced by a load moving on a flexible suspension. Increasing the damping capabilities of control systems leads to a reduction in the load on both the electrical and mechanical parts of the crane. There is also an increase in the reliability of the structure as a whole and the safety of its maintenance and operation. The work proposes a method for limiting load oscillations, one is based on regulating the acceleration of the trolley through corrective feedback signals using a block operating according to the rules of fuzzy logic. The use of the proposed system showed good results.
