Status of the feedforward GLA design methodology (CS2-AIR-KO-A-4.2.1-4)

Abstract

This report contains the current status of the work performed by the NACOR consortium on lidar-based feedforward load alleviation within the work package CS2-AIR-WP4.2.1. At the end of 2018 the status can be summarized as follows: - The real-time LIDAR simulation (surrogate model) and the wind reconstruction algorithm are ready and tested. - A new physics-based end-to-end simulation framework allowing to determine the values for the parameter of the surrogate LIDAR model based on the physical sensor characteristics is being developed with a new PhD thesis (started in 2018) and that will lead to a significantly improved representativeness of the overall results. - The progress on the definition of the control design methodology for the feedforward load alleviation is now around 50%. This methodology will be finalized and validated by the end of 2019 / beginning of 2020. Several scientific papers on the different aspects of the lidar-based feedforward load alleviation (overall setup, tuning etc.) were already published, including 3 journal papers (2 published, 1 accepted but not published yet) and various conference/workshop contributions. Further publications on this work will be produced in 2019 and in the following years.
