Abstract
In order to solve the output voltage ripple problem caused by load variation of magnetic suspended attitude control and energy storage flywheel (ACESFW) energy conversion system, a PI synergetic control method for the parallel DC-DC Buck converter is presented in this paper. The method applies two synergetic controllers in current loop, each controller obtaining current reference from average value of output of PI voltage controller which overcomes shortcomings such as poor adaptability and robustness of basic synergetic control method. Simulation and experimental results show that the presented method has highly stable output voltage, small ripple and perfect robustness.
