IP decoupling control for DFIG based on support vector machines

To solve the coupling problem in DFIG with multivariable control system, a new decoupling method based on support vector machines is proposed. The decoupled active power and reactive power in M-T frame was controlled with IP controller. Power control scheme is designed and the structure diagram is given. Simulation and experiment is implemented with the corresponding parameters, which made the waveform diagram of identification error, current and voltage obtained. The coincidence between the simulation result and the experiment result proves the correctness and validity of the new method.
