Abstract：

This　paper　presents　a　model　predictive　control　(MPC)　method　of　two-stage　rectifier　based　on　linear　extended　state　observer　(LESO).　The　control　performance　of　conventional　MPC　is　easy　to　be　affected　under　parameter　mismatches　and　external　perturbation　condition.　To　solve　this　problem,　the　LESOs　are　designed　to　observe　the　system　lumped　disturbances.　Then,　predictive　model　would　be　compensated　by　the　observed　values　to　improve　the　accuracy　in　one　period.　The　cost　function　of　MPC　is　evaluated　by　the　method　of　deadbeat　control.　Furthermore,　to　reduce　the　current　ripple,　the　carrier　phase　shifting　pulse　width　modulation　(CPS-PWM)　is　applied.　The　simulation　results　validate　the　strong　robustness　and　better　dynamic　performance　in　two-stage　rectifier　compared　with　conventional　method.　©　2021　IEEE.
