Recent work has demonstrated the benefits of preview wind measurements for turbine control. This paper investigates the basic design trade-offs between turbine performance, preview time, and pitch actuator rate limits. A Region 3 rotorspeed tracking problem is formulated in continuous-time as an optimal control problem using a simple one-state rigid body turbine model. The exact, analytical solution to this problem provides insight into the fundamental performance limits. These analyticaldoi:10.1109/tcst.2013.2261069 fatcat:sfcew63o2vgafankxsmb6s5i4e
