| Abstract |
In this paper, Application and Comparative Analysis of Anti-windup Method for Improving the Stability of Voltage Control of Auxiliary Power Supplies in Railway System. Because it is easy to design, and the structure is simple, there is a problem in the widely used PI controller to occur. Various problems occur, such as response time delay and overshoot due to integrator windup caused by the accumulation of errors in the integral controller. To improve this, various anti-windup methods have been studied.
Among the representative Anti-windup methods, it was checked whether various problems caused by integrator windup could be solved through the conditional integral Anti-windup method and the tracking Anti-windup method and the error control Anti-windup.
After confirming through PSIM simulation before hardware experiment, DC power conversion system was designed and improvements were confirmed. |
