With the gradual increase in the size and flexibility of composite blades in large wind turbines,problems related toaeroelastic instability and blade vibration are becoming increasingly more *** their impact on thelifespan of wind turbines,these subjects have become important topics in turbine blade *** this article,firstaspects related to the aeroelastic(structural and aerodynamic)modeling of large wind turbine blades are ***,two main methods for blade vibration control are outlined(passive control and active control),including the case of composite *** improvement schemes are proposed accordingly,with a specialfocus on the industry’s outstanding suppression scheme for stall-induced nonlinear flutter and a new high-frequencymicro-vibration control ***,future research directions are indicated based on existingresearch.
