摘要：
This study discusses a simple sliding surface design approach of a reduced-order sliding mode controller (ROSMC) for power factor correction, wherein a new and systematic technique for the selection of sliding surface co-efficients to implement ROSMC is attempted. Pade's approximation technique is used to obtain the reduced-order model. A prototype of front-end AC-DC converter followed by DC-DC Cuk converter controlled by ROSMC using a dSPACE signal processor is set up for 60 W. Experimental results are presented to validate the simulation results. Simulation and experimental results reveal that ROSMC control can achieve good output voltage regulation and also provide improved robustness in shaping the input current in the presence of load variations.
