Maximum Power Improvement Active Disturbance Rejection Control for Wind Turbines

Aiming at the problems of linear active disturbance rejection control (LADRC) in the permanent magnet direct - drive wind power generation system, such as non-full decoupling between dynamic and immunity performance and poor observation accuracy, an improved active disturbance rejection control method with a compensation function observer (CFO - LADRC) is proposed. A speed controller with CFO - LADRC is designed based on maximum power tracking with the optimal tip speed ratio, resolving the performance trade-off and improving immunity. Frequency domain analysis shows that it’s better than conventional LADRC. Simulation comparison reveals that it can effectively enhance the anti - disturbance ability while retaining the advantages of the conventional method.
