英文摘要：

A new outer loop control method for the three-phase voltage rectifier was proposed.The traditional PI model was analyzed,which was improved to be a single neuron control based on the load current feed forward model.Through modifying the weights automatically,the control goal was achieved.Its stability was proved by designing the Lyapunov function.This method is simple to apply and easy to realize.Its feasibility and robustness were verified by simulation experiments.
