Pitch angle control for horizontal axis wind turbine: A comparative study

Wind Energy is a promising sector which has a rapid growth over a recent few years. Hence a fault tolerant and optimized control system of a wind turbine is propitious as it secures the energy production. The nonlinear multidisciplinary physical modelling should be built which is convenient and seemly legit for the purpose of control analysis. Including the effect of wind shear and tower shadow in the aerodynamic module, adding a dynamic model in the drive train module and their integration along with the energy monitoring is taken for a significance of the present work. In light of this, Classical PID control, Fuzzy logic control and a gain scheduled PID control were designed to correct the deviations in the pitch perturbation for above-rated wind speed. Also to sustain the power generation of the turbine, MPPT controller was implemented to the generator. The dynamic model was built using Simscape in the MATLAB/Simulink Environment and a comparative study was done to evaluate the performance of different controllers.
