摘要
A multi-loop switching control system for a doubly-fed wind turbine based on logic switch control. Output variables of the doubly-fed wind turbine may be used to form output feedback control channels. Each output feedback control channel may switch between a switch controller and a vector controller to form a multi-loop switching controller. When a power system associated with the doubly-fed wind turbine is subjected to a relatively large external disturbance, state variables and the output variables of the wind turbine deviate from an original balance point, and the output feedback control loops of the doubly-fed wind turbine are switched from the vector controller to the switch controller. Under control of the switch controller, the state variables and output variables return to a vicinity of the original balance point, and the output feedback control loops of the wind turbine are switched from the switch controller to the vector controller.
