Abstract :
This paper presents a nonlinear control strategy for unified power quality conditioner(UPQC) with better stability and dynamic performance in comparison with PI control and classical decoupled strategy. The analysis is based on the rotating reference frame, and the nonlinear property of UPQC mode is partly dealt through the exact linearization via feedback. The operation of control circuit has been explained using MATLAB software and simulation. The validity of control strategy is studied through simulation results.
