More Information
Summary:The invention discloses a fan control system adopting variable-structure PID variable-propeller control, which comprises a variable-propeller-pitch range computing module, a gust protection processing module, a rotating speed deviation filtering module, a segmented PID regulating module, a variable-propeller-pitch speed nonlinear factor computing module and an output control module. In the invention, the rotating speed of a generator is accurately controlled through the PID regulation for rotating speed deviation, and the fan control system has stable and reliable performance, can effectivelyimprove the output power of a fan and has the advantages of excellent performance, safety and stability.
