摘　　要：根据结构振动模糊控制原理,提出了模糊PID振动控制算法,兼顾了PID控制的特点,同时也可以减少所需要的模糊推理数量。建立了一栋20层结构地震动力反应振型模糊控制的分析模型,并利用Matlab语言编制了求解软件。计算结果表明:模糊PID振型模糊控制算法对层间位移、楼层位移和楼层加速度有较明显的减震效果,在控制力一定的情况下,调整其参数指标pidmax,只对第一模态控制就可以达到较好的减震效果。且减震效率沿房屋高度分布均匀。利用模糊PID算法控制得到良好的减震效果。According to fuzzy control algorithm for structural vibration,the active fuzzy PID control algorithm is put forward,in consideration for general PID control algorithm and reduction for fuzzy logic reasoning.Then a numerical analysis model of vibration fuzzy control of a 20 story structure is established,and the solution software is programmed with MATLAB language.The results show that the fuzzy PID control algorithm has notable seismic mitigation efficiency on inter-storey displacement,storey displacement and storey acceleration.With the control force being kept constant,a satisfied seismic mitigation efficiency can be achieved by adjusting its parameter pidmax,even only for the first mode control.Moreover the seismic mitigation efficiency is evenly distributed along the structural height.It is concluded that fuzzy PID algorithm could exhibit good performance for structural seismic mitigation.
