Research on Hydraulic Pitch-Control System of Wind Turbine
Applied Mechanics and Materials, 2013It is usually difficult to establish an accurate mathematical model for hydraulic servo system because of its complicated and non-linear properties. However, bond-graph method has its unique advantages in modeling such as processing multiple energy conversions.

Analysis of the Hydraulic Impact of the Wind Turbine Hydraulic Yaw Brake System
International Journal of Multimedia and Ubiquitous Engineering, 2016When the wind turbine hydraulic yaw system brake and pressure relief, hydraulic oil pressure in the hydraulic system is rapidly reduced, and its direction of flow has also undergone dramatic change. Hydraulic impact generated easily make equipment failure by mutations pressure in pipeline. For there is the larger hydraulic impact problem when hydraulic

Neural Predictive Controller for Hydraulic Power Transmission in Wind Turbine
ASME 2014 Gas Turbine India Conference, 2014Fluid power transmission for wind turbines is quietly gaining more interest. The aerodynamic torque of the rotor blades is converted into a pressurized fluid flow by means of a positive displacement pump. At the other end of the fluid power circuit, the pressurized flow is converted back to torque and speed by a hydraulic motor.
