Improved Model Predictive Control for Regulation of Boost Converter under Parametric and Input Voltage Variation

This study proposes an improved model predictive control (IMPC) for voltage regulation of a practical DC-DC boost converter (DBC). This paper develops the design of discrete-time (DT) DBC subject to parametric, load, and input voltage variations. An improved model-based predictive control is proposed based on a linearized model of DBC around the nominal operating point. The difference between the actual output from the DBC and the output from the mathematical model is utilized to include a new corrective term in the predicted output, which is further used to generate an optimal control sequence while considering constraints. The validation of the proposed control is presented via simulation
