Intelligent Control for the Variable-Speed Variable-Pitch Wind Energy System
In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...
متن کاملControl Strategies for Variable-speed Fixed-pitch Wind Turbines
This chapter deals with a design of controllers for variable-speed fixed-pitch wind turbines. The chapter begins with an introduction to wind turbine control and the detail of nonlinear models of the wind energy conversion system (WECS). Linearization around a set of equilibrium points is presented to obtain a linear parameter variable model from a nonlinear system. Open-loop characteristics fo...
متن کاملFuzzy gain scheduled output feedback control for variable-speed variable-pitch wind turbine
This paper proposes a fuzzy gain scheduled output feedback control for variable-speed variable-pitch wind turbine in full load region. The proposed method is based on modeling the nonlinear system as a family of systems linearized around a specific operating point. The goal is to design optimal PI controllers based on linear models and a fuzzy scheduler. The parameters of each PI controller are...
