This work lays out the methodology of the analysis and consequent control design for the LC filter application on the example of a 5 MW wind turbine. The chapters progress sequentially through the different complexity steps from the continuous analysis to the discrete-space modeling to control algorithm design, integrated into a microcontroller-based hardware setup. The methods in each complexity step illustrate the process, starting with the identification of the control issue, through the control solutions, and ending with the evaluation using dynamic analysis.
