The Study of Three-phase PWM Rectifier with Complex Vectors of Decoupling Control
In order to overcome the defects of the difficulty to zero steady-state error condition, a control strategy using d-q transformation which the three phase variable is converted into d-q synchronous rotation coordinates to control is proposed. However, due to the problems of system in d-q axis variable coupling, the A strong dependence between the design of controller and system parameters ,leading to the original system control performance will decrease sharply, because of the values changing of AC filter inductor reasons for aging changes. In this paper, the control strategy is proposed through complex vector Linear d-q decoupling, the double closed loop control strategy is improved through in the d-q synchronous frame, the design method of the double closed loop control model is analyzed. The simulation analysis results demonstrate the simplicity of the proposed model structure, the strong self-adaptability.
