Fuzzy control process for quick damping of mechanical vibration and for positioning, device therefor and fuzzy control positioning device

PROBLEM TO BE SOLVED: To provide a fuzzy control process for quick damping of mechanical vibration and for positioning and device therefor. SOLUTION: The device includes two fuzzy controllers 10, 11 to provide a control signal based on the measurement of position and vibration. The process includes processing that deformation of a mechanical element and a position thereof are measured, a position error and a vibration error are generated through the comparison with a reference value, a differentiated value of the position error and a differentiated value of the vibration error are generated, fuzzy control is applied to the position error and the vibration error, the differentiated value of the position error and the differentiated value of the vibration error to generate a proper control signal (u) to drive the mechanical element 1.
