Fuzzy control process and device for positioning and quickly damping mechanical oscillations

摘要

A fuzzy control process for positioning and quickly damping mechanical oscillations comprising the following steps: measuring a value of the position of a mechanical element (1); generating a position error (Ey) from the comparison between the position value (y) and a first reference value (yref); measuring a value (v) of the deformation of the mechanical element (1); generating a vibration error (Ev) from the comparison between the deformation value (v) and a second reference value (vref); generating the derivative (dEy/dt) of the position error. The particularity of the invention resides in the fact that it comprises the additional steps of: generating the derivative (dEv/dt) of the vibration error (Ev); applying a fuzzy control to the position error (Ey), to the vibration error (Ev), to the derivative (dEy/dt) of the position error, and to the derivative (dEv/dt) of the vibration error, so as to generate a control signal (u) that is suitable to drive means (2) for actuating the mechanical element (1). $$
