In this paper we design and analyze a full-information H∞ controller to in order to reduce the wake meandering behind a wind turbine. The low frequency instability that causes wake meandering can cause unsteady mechanical loads on the downstream turbines resulting in early onset of material fatigue. Controlling the wake meandering in a wind farm can therefore reduce maintenance costs. The control...
The paper considers a general approach for gain scheduling of Lipschitz continuous nonlinear systems. The approach is based on a linear parameter varying system (LPV) representation of the nonlinear dynamics along with integral quadratic constraints (IQC) to account for the linearization errors. Past results have shown that Jacobian linearization leads to hidden coupling terms in the controlled system...
