Abstract :
The dynamic characteristic of traditional controllers is not good enough especially when DC voltage sags or load changes abruptly. Plus, static error would be generated if the input is an AC signal. In this paper, PR controller is used to solve above problems. This article presents the transfer function of PR controller by theoretical analysis, At last, both simulation and experiment achieved the regulatory role by DSP demonstrate that PR controller can eliminate static error and has a good dynamic performance.
