Abstract:
The industry energy is currently facing many challenges. The mostimportant one concerns the use of
conventional energy sources which have a direct impact on increasing global warming. With a view of reducing the
emission of greenhouse gases, sharing renewable energy and increasing our energy efficiency by transforming
energy and introducing clean renewable energies that are not implemented in the field of energy, electricity
production is no longer a matter of choice it becamean obligation for nation’s energy policy.
In this context, to increase the durability and efficiency of the electric switching system of renewable energy on
the one hand, and to improve the quality of energy supplied on the other, the purpose of the work presented in this
thesis is primarily the implementation of high-performance nonlinear control law on asynchronous machine,
secondly the improvement of process paths with disturbance rejection and finally ensuring stability and maintaining
the disconnection between flow and torque despite changes in machine parameters.
The simulation resultsobtained for motor operation show that the nonlinear and sliding mode control have best
dynamic performance compared to those obtained through the application ofother control techniques.
The best dynamic performances of the sliding mode control wereconfirmed by the implementation of this
technique intocontrol scheme of the active and reactive power of doubly fed induction generator driven by wind
turbine.The simulation results confirmthe exact decoupling and good trajectory tracking of the active and reactive
power.
