Robust Controller Based on Sliding Mode Technique of DFIG Integrated to Wind Energy System

The object of this work is designing a robust controller based on sliding mode technique of DFIG for using in wind turbine system. The conventional control of DFIG, such as vector control is very sensitive when the electrical and mechanical parameter are changed, to solve the problem of the vector control, the theory of sliding mode control is presented in brief, then it applied to the control of active and reactive power of DFIG. The simulation results prove that the implementation of the sliding mode controllers for active and reactive powerloops leads to good dynamic performance even with large electrical parameters change.
