A Comparative Study of the ADRC and PI Controller of a Wind Turbine Driven by a PMSG

The world is currently experiencing a huge shortage of energy sources, and global energy needs are constantly increasing due to the pace of industrialization and the improvement in the people’s living standards. Safer and less polluting renewable energies such as solar energy or wind power are the two most appropriate solutions now. The aim of this research is to study wind energy knowing its functionalities and characteristics, through an aerodynamic machine based on a permanent magnet synchronous generator (PMSG), which has advantages manifested in the absence of an excitation circuit and the lack of speed multiplier. This chapter involves modeling of the different components of the conversion chain, in order to extract the mechanical and electrical control equations. The control of the converters is ensured by the PI control, and also by another robust control named Active Disturbance Rejection Control (ADRC), taking into account obtaining maximum energy by the use of the Maximum Power Point Tracking (MPPT). The simulations are carried out in the MATLAB/SIMULINK environment with a comparison between the two control methods. According to the results obtained, the effectiveness of the ADRC control is shown.
