VIBRATION CONTROL OF A TRANSLATING BEAM WITH AN ACTIVE CONTROL STRATEGY ON THE BASIS OF THE FUZZY SLIDING MODE CONTROL

摘要

An active control strategy is developed for nonlinear vibration control of an axially translating beam applied in engineering field. The control strategy is established on the basis of Fuzzy Sliding Mode Control. The nonlinear model governing the beam system is described with a six-degree nonlinear dynamic system. Corresponding to the multi-degree nonlinear system, the active control strategy is developed. The proposed control strategy is proven to be effective in controlling and stabilizing the nonlinear motions especially chaotic motion of the beam.
