Fuzzy vibration isolation control for a new type of floating raft
一种新型浮筏的模糊减振控制

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.
