In　order　to　improve　dynamic　performance　and　robustness　of　interleaved　boost　converter,　this　paper　proposes　a　predictive　control　strategy　based　on　deadbeat　method　using　Luenberger　disturbance　observer　(LDO).　To　solve　the　problem　of　modeling　inaccuracy　under　the　condition　of　input　voltage　fluctuation　and　unknown　inductor　equivalent　series　resistance,　a　LDO　is　designed　to　observe　the　lumped　disturbance　and　compensate　the　predictive　model.　Subsequently,　another　LDO　is　proposed　to　estimate　load　equivalent　resistance　to　enhance　the　robustness　under　load　perturbation　condition.　Furthermore,　the　carrier　phase　shifting　pulse　width　modulation　(CPS-PWM)　is　used　to　reduce　output　current　ripple　combining　with　interleaved　topology.　The　simulation　results　verify　the　excellent　dynamic　performance　and　robustness　of　proposed　method.　©　2021　IEEE.
