Abstract:
The strong randomness of wind speed and the uncertainty of wind turbine modeling bring about great challenges to the disturbance attenuation of wind turbine system. In this paper,a new type of non-linear sample-data controller is designed to realize the output power to suppress the disturbance signal. Firstly,the non-linearity and disturbance in the system are equivalent to bounded terms,and the approximate mathematical model of the system is established. Secondly,a continuous state feedback controller is designed to estimate the suppression gain. Thirdly,a sampling controller is constructed to meet the stability requirements and disturbance suppression,which is easy to implement in computer. Finally,the stability and disturbance suppression characteristics of the sampled-data controller are verified by a cosine disturbance input example.
