  • Patent number: 9391554
    Abstract: Aspects of the disclosure relate to a control approach that utilizes a direct-current-based d-q vector control technology for variable-speed PMSG wind turbines based on full voltage source PWM converters. The control approach can be based on a nonlinear programming configuration for attaining a desired performance of PMSG wind turbine under operation constraints. The control approach can comprise a PMSG control unit that exploits fuzzy, adaptive, and PID control technologies in an optimal or nearly optimal control configuration. The control approach provides a smart wind turbine control technology that can be based on virtual lookup tables for effective PMSG power extraction.
