N2 - To achieve real-time estimation and compensation of total system disturbances and improve the control performance of wind turbines under complex turbulent wind conditions, three one-order LADRCs were used to reconstruct the wind turbine core control system. A dynamic variable limit LADRC was designed for torque control, a minimum limit LADRC was applied in pitch control, and a LADRC power controller was designed for decoupling torque and pitch control. The stability of the LADRCs was proven using the Lyapunov method. According to the transfer function of wind turbines and empirical equations, the parameters of each LADRC were tuned. Based on the hardware-in-loop simulation (HILS) test platform, the control algorithm of look-up table, PID, RISC, and LADRC were constructed by PLC language. Through comparative studies, it was verified that the algorithm proposed in this paper can reduce generator rotor speed and power fluctuations by about 13.6% and 1.7% at least, and it can also reduce the blade root load force.
