Active disturbance rejection variable pitch control based on sparrow optimization

One of the essential technologies for wind energy utilization is adjusting the propeller's pitch. To address the challenges of PID-controlled variable pitch, ADRC is integrated into the variable pitch controller, resulting in the design of a speed-loop controlled variable pitch system. Beyond the rated wind speed, the system relies on speed as a feedback signal to maintain stable output power at the rated level. The parameters of the variable pitch controller are self-optimized using the Sparrow optimization algorithm. By utilizing MATLAB/Simulink simulation software, we conduct simulations on the variable pitch controller and its associated algorithm. The simulation results show that when the Sparrow algorithm is implemented in the controller, not only does optimization occur rapidly, but also the convergence speed is increased, further enhancing the system's anti-interference capabilities.
