Research on Model Predictive Control of Interleaved Boost Converter

Interleaved boost converter is widely used in the power system of fuel cell electric vehicles to prolong its lifespan and convert low voltage electricity to high voltage electricity. The discrete time domain model is established, and the predictive model is obtained to design inner loop model predictive control. An outer loop active disturbance rejection control is designed to compensate current reference to eliminate the influence of model mismatch. Then the results of different disturbances under the proposed controller are compared with super-twisting (ST) and PI controller by simulation. Finally, it is concluded that the proposed controller has better robustness and following performance.
