Optimal vibration control and simulation for gearbox of wind turbine
The optimal vibration control and simulation problem of wind turbine gearbox system is studied. A nonlinear, coupling and uncertain dynamic model of the wind turbine gearbox is considered. Because it is difficult to design the controller for the wind turbine gearbox control system, the nonlinear and coupling uncertain control system is simplified, and a linear model is obtained. Then, based on optimal control approach, an optimal controller is designed for the wind turbine gearbox. Numerical simulations illustrate the effectiveness of the proposed controller.
