Research on fractional terminal sliding mode electro-hydraulic pitch control method based on perturbation observer
摘要
Abstract
In order to improve the control performance of wind turbine electro-hydraulic pitch system,a fractional terminal sliding mode control method based on perturbation observer is proposed.The mathematical model of the wind turbine electro-hydraulic pitch system is established,and the sliding-mode state and perturbation observer is used to compensate the uncertainty and unknown disturbance of the pitch system parameters in real time.Fractional calculus theory is used to design the sliding mode surface of the terminal sliding mode controller,which can improve the jitter of the sliding mode control itself while ensuring the finite time convergence.Simulink is used for experimental verification,and the results show that the method enhances the anti-interference ability of the pitch system,weakens the jitter of the system,improves the tracking accuracy of the pitch angle,and improves the stability of the pitch system.关键词
