摘要: 在采用模糊控制的压电材料智能结构中,利用遗传算法对模糊控制隶属函数进行优化时,遗传编码的设计将影响优化结果,从振动主动控制要求出发,设计了振幅输入模糊集的隶属函数参数编码,并对模糊子集约束条件进行处理。结果表明新的编码方式可以产生适合振动主动控制的隶属函数,且设计的约束修补算法简单有效。

Abstract: When the genetic nlgorithms ure.used to optimize the fuzzy logic controller, which is used for active vibratioti suppression, the encoding method is important for the results, According to the requirement of vibration controL an encading method is presented for the membership functions of fuzzy logic control. Furthermore. The constraintproblem is considered and solved. The numeric result shows that this encoding method can generate good individuals suitable for the requirement of active vibration control, and the amending algorithm for the constraint problem is simple and effective.
