A Youla-Kucera approach to gain-scheduling with application to wind turbine control

This paper addresses bumpless transfer between observer-based controllers with integral action in a gain-scheduling architecture with application to wind turbine control. Two methods based on the Youla-Kucera parameterization are applied to achieve bumpless transfer between controllers having equal or different number of control signals and integrators while preserving stability guarantees. Both methods handle reference signals to the controllers.
