一种新型浮筏的模糊减振控制

本文针对带有电流变液智能阻尼器的新型浮筏装置提出了前馈和反馈两种模糊控制策略并进行了实验研究.前馈模糊控制策略根据浮筏所受到的振动激励信号的主频特性来确定模糊控制器的控制规则,反馈模糊控制策略则是根据簧载质量的位移响应来制定控制规则,二者的最终目的都是通过模糊控制算法来得到最优的电流变液阻尼器控制电压,达到期望的隔振效果.实验结果证明,两种模糊控制策略控制下的浮筏隔振系统的隔振性能都要远远好于传统的最优被动浮筏隔振系统.

Fuzzy vibration isolation control for a new type of floating raft

Two fuzzy control methods are proposed to control a new type of floating raft whose damper could be adjusted with the voltage.The first is a feed forward fuzzy control method whose rules are made by analyzing the main frequency of the excited signal.The second fuzzy control method is a feedback control method whose rules are made according to the displacement of the spring-loaded mass.The objective of the methods is to apply a maximum control voltage to the damper to achieve the best vibration isolation effect of the floating raft.The experiment has indicated that the proposed control methods are very effective in vibration isolation than the passive optimal system through the experimental results.
