Nonlinear control of variable-speed wind energy conversion system

Abstract This paper discusses the nonlinear control problem for variable-speed wind energy conversion system. Due to the stochastic operating conditions and the inevitable uncertainties inherent in the system, linear control method comes at the price of poor system performance and low reliability. So, it first develops a detailed model of variable-speed wind energy conversion system, which incorporated a distributed generation and then applies the Multiple Sliding Surface designing controller for robust performance of optimizing the generator converter system efficiency.
