A New Nonsmooth Optimal Control Framework for Wind Turbine Power Systems
Hesham Abdelfattah, Sameh A. Eisa, Peter Stechlinski
Optimal control theory extending from the calculus of variations has not been used to study the wind turbine power system (WTPS) control problem, which aims at achieving two target…
