Fuzzy Adaptive

In order to suppress the vibration of large-scale flexible structures which are applied on the spacecraft, a semi-active control method based on fuzzy adaptive SSDV (synchronized switch damping on voltage) technique is proposed. The value of voltage source at the switching moment is adjusted adaptively by using fuzzy logic, in order to improve the stability and control precision of the semi-active control system. The feasibility of this method is verified by two kinds of experiments with typical disturbance conditions. By comparing different adaptive displacement-voltage curves, the fuzzy adaptive method can achieve higher control precision. For the initial displacement disturbance of 10 mm, the fuzzy adaptive SSDV method can increase the system damping ratio from 0.6% to 5.1%. The control effect decreases with the increase of initial displacement. For the disturbance caused by the mechanism at the tip position, the method can effectively shorten the vibration damping time and reduce the displacement from 0.3 mm to 0.04 mm.
