Luenberger Disturbance Observer-Based Deadbeat Predictive Control for Interleaved Boost Converter

A cascaded deadbeat predictive control strategy with online disturbance compensation is proposed for a three-phase interleaved boost converter in this paper. The topology of the symmetric, so inner loop controller also designed symmetrically. For purpose realizing error-free tracking reference value, method adopted and outer loops Luenberger observers, which are to estimate compensate disturbances load variation power model as well unknown resistor inductance current model. To eliminate influence time delay, two-step In aspect parameter design, pole placement determine gain observer. series simulations experiments carried out test under steady dynamic conditions. It shown that has faster response stronger robustness against than conventional control.
