摘　　要：为消除风电叶片疲劳试验过程中两激振器间的耦合影响,提高两激振器的同步控制性能,设计虚拟主轴并行同步控制策略。应用模糊PI控制算法设计相位控制器,并搭建风电叶片两点惯性激振同步控制试验平台,验证该算法的同步控制效果。结果表明:在非同步控制状态下,两激振器间存在耦合效应,导致相位差存在较大波动,难以实现两激振器联合激振,叶片振幅紊乱,不满足叶片疲劳试验的要求;在同步控制状态下,实现了两激振器良好的同步控制效果,叶片振幅稳定,相位差值为±1.5°。To eliminate the coupling effect between the two vibration exciters during the fatigue test of wind turbine blades and improve the synchronous control performance of the two exciters,the parallell synchronization control strategy of virtual spindle was designed.The fuzzy PI control algorithm was applied to design a phase controller,and a two-point inertial excitation synchronous control test platform was built to verify the synchronous control effect of the algorithm.The results show that in the non-synchronous control state,there is a coupling effect between the two exciters,and there is a large phase difference fluctuation between the two exciters,which is difficult to realize the joint excitation of the two exciters,and the blade amplitude is disordered and not satisfied the requirements for blade fatigue test;in the synchronous control state,a good synchronous control effect of the two exciters is realized,the blade amplitude is stable,and the phase difference is within±1.5°.
