Research on Hydraulic Pitch-Control System of Wind Turbine

Abstract:

It 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. Furthermore, good results could be achieved by combining fuzzy control with normal PID control. As a result of air current load interfering with the system in changeable and complicated environment, process control is obviously important. Taking 1MW wind turbine pitch-control system as an example, a simulation research based on the above method is conducted.
