A novel PIλDμ controller and its application in UPQC DC voltage control

Abstract

UPQC is a powerful application to settle the Power Quality problem. The DC voltage being the given value is the prime of its correct and valid working. The principle and the advantage of Pi^lambdaD^mu controller are presented in this paper. By using the software MATLAB and EMTDC/PSCAD, the Pi^lambdaD^mu controller and the UPQC are simulated separately. The Pi^lambdaD^mu control of the DC voltage is the utilized through the interface of the MATLAB and EMTDC/PSCAD software. Simulation results show the validity and correctness of the Pi^lambdaD^mu controller and it is advantaged than the traditional PI control. The Pi^lambdaD^mu controller would be widely used in Power System and other systems.
