Optimization of Cyclic Pitch Control for a Vertical Axis Wind Turbine

In this report, the issue of pitch control in a Vertical Axis Wind Turbine is tackled. By using and aerodynamic model, a theoretical optimum pitch solution is found and then a simple four-bar mechanism is adapted to that theoretical solution to achieve a simple and elegant control of the pitch in the turbine. The model used is the Actuator Cylinder model. Another aspect that is studied is the possibility of self-start of the turbine by only changing the pitch on the blades. All analyses conducted are done for a specific wind turbine.European Wind Energy Masters (EWEM
