摘要
According to the problem of the three-phase inverter output slow dynamic response speed, high THD when load mutation and with nonliner dynamiac with the ordinary PID control algorithm, this paper propouses a sheme that the naural network intelligent algorithm for tuning ring(voltage loop) of PI parameter based on the double closed loop controlalgorithm. First, a dual Boost PFC is designed, and the mathematical model of the controlled object is built. the PID controller based on RBF and the LC filter circuit are designed. Finally, the 10KVA online UPS is taken as an example to verify the simulation. The simulation results show the correctness and effectiveness of the proposed scheme.
