Abstract EN
This paper considers the neural network controller design problem for variable pitch wind energy conversion systems (WECS) with non-Gaussian wind speed disturbances in the stochastic distribution control framework.
The approach here is used to directly model the unknown control law based on a fixed neural network (the number of layers and nodes in a neural network is fixed) without the need to construct a separate model for the WECS.
In order to characterize the randomness of the WECS, a generalized minimum entropy criterion is established to train connection weights of the neural network.
For the train purpose, both kernel density estimation method and sliding window technique are adopted to estimate the PDF of tracking error and entropies.
Due to the unknown process dynamics, the gradient of the objective function in a gradient-descent-type algorithm is estimated using an incremental perturbation method.
The proposed approach is illustrated on a simulated WECS with non-Gaussian wind speed.
