Abstract EN
The aim of this paper is to analyze aeroelastic stability, especially flutter suppression for aeroelastic instability.
Effects of aeroservoelastic pitch control for flutter suppression on wind turbine blade section subjected to combined flap and lag motions are rarely studied.
The work is dedicated to solving destructive flapwise and edgewise instability of stall-induced flutter of wind turbine blade by aeroservoelastic pitch control.
The aeroelastic governing equations combine a flap/lag structural model and an unsteady nonlinear aerodynamic model.
The nonlinear resulting equations are linearized by small perturbation about the equilibrium point.
The instability characteristics of stall-induced flap/lag flutter are investigated.
Pitch actuator is described by a second-order model.
The aeroservoelastic control is analyzed by three types of optimal PID controllers, two types of fuzzy PID controllers, and neural network PID controllers.
The fuzzy controllers are developed based on Sugeno model and intuition method with good results achieved.
A single neuron PID control strategy with improved Hebb learning algorithm and a radial basic function neural network PID algorithm are applied and performed well in the range of extreme wind speeds.
