This paper proposes a novel sliding mode control (SMC) technique for doubly fed induction generators (DFIGs) based on the fast exponential reaching law (FERL). The proposed FERL-based SMC is capable of reducing to a large extent the chattering phenomena existing in the sliding stage. Meanwhile, the reaching stage is accelerated with the introduction of an adaptive gain. The proposed method is employed in a DFIG-based wind energy conversion system (WECS) for direct power control (DPC). The FERL-based DPC approach is tested with simulations conducted in Matlab/Simulink under the scenarios of unbalanced grid voltage, grid fault conditions and highly unstable wind speed accompanied by an experimental study. The simulations and experimental results reveal the better performance of the proposed control method in active/reactive power tracking and dc-link voltage maintenance.

“…Due to such configuration, DFIG-based WE systems here after mentioned as (DFIG_WES) is sensitive towards grid disturbances and the nature of wind speed. [3][4][5] As the wind speed and the disturbances in the grid are very dynamic in nature, enriched controllers such as the vector control (VC), direct torque control (DTC), and direct power control (DPC) with advanced techniques are employed. A vector controlled operation is the most adapted technique for DFIG_WES.…”

Summary This paper presents the analysis and design of artificial neural network (ANN) and proportional and integral (PI) controller‐based hybrid control (HC) of doubly fed induction generator (DFIG). The proposed HC gives the quick dynamic and good transient response during the sudden changes in wind speed. Further performance of proposed hybrid controller has been analyzed independently with ANN and PI control as its components. The HC with ANN gives better performance compared with conventional direct torque control (CDTC) and PI DTC in terms of flux ripples, torque ripples, and settling time. The proposed technique is implemented in real‐time simulator (RTS)‐based OPAL‐RT and MATLALAB/SIMULINK environment at a rating of 5.5‐kW system under step and randomly change in wind velocity.

Resumo -Neste artigo é proposto um algoritmo de controle direto de potência, operando a velocidade variável e robusto às variações nos parâmetros de um gerador de indução duplamente alimentado, cuja aplicação é realizada em sistemas eólicos em condições normais de operação. O controlador possui duas malhas de controle: uma para o desacoplamento do fluxo do estator e outra malha de controle Deadbeat. O controlador calcula o vetor de tensão fornecido ao rotor a fim de garantir que a potência ativa e reativa atinjam seus valores de referência desejados. A dependência do algoritmo às variações dos parâmetros foi investigada, assim como a influência dos erros na estimativa desses parâmetros. Simulações em Matlab/Simulink e testes com uma bancada experimental foram feitos para analisar a eficácia do algoritmo proposto.Palavras-chave -Controle Deadbeat, Controle Direto de Potência, Energia Eólica, Gerador de Indução Duplamente Alimentado. A DEADBEAT DIRECT POWER AND DECOUPLED STATOR FLUX CONTROL FOR DFIGAbstract -This paper proposes a direct power control algorithm, operating at variable speed and robust to parameter variations for a Doubly Fed Induction Generator-based wind power generation system. This scheme uses two control loops, one for decoupled stator flux and another one for Deadbeat direct power controller. The control algorithm estimates the voltage vectors to be supplied to the rotor in order to guarantee that active and reactive powers reach their desired reference values. The algorithm parameter dependence and their variations were investigated, together with the influence of the estimation errors for these parameters. Simulations in Matlab/Simulink and experimental results are carried out to validate the effectiveness of the proposed controller during normal operation conditions.
