Here’s a very small article from Acromag positionning its FPGA products toward smart-grid and Wind Turbine Control applications.
“The basic components of a control system to maximize energy capture from a wind turbine include: rotor pointing, blade speed regulation, minimization of pointing and pitch control, and the mitigation of disturbances (i.e. excessive rotor speed, wind gusts, etc.). Additionally, the environment inside the rotor head, or nacelle, is very hostile. Any control device used in this environment must be self-diagnostic, rebootable, extreme temperature tolerant, vibration tolerant, and of course, affordable.”
