Dynamic Phasor Model Predictive Control of Switched Mode Power Converters


S. Almér, S. Mariéthoz, M. Morari

IEEE Transactions on Control Systems Technology, vol. 23, no. 1, pp. 349 - 356

The paper considers model predictive control of switched mode power converters and uses a hybrid prediction model which represents the switching ripple of the converter state. The goal of the approach is to achieve both high dynamic performance and low harmonic distortion of the output at steady state. It is argued that previously published approaches to hybrid model predictive control of power converters are sensitive to plant/model mismatch, and an alternative problem formulation is suggested. The new formulation describes the converter state in terms of dynamic Fourier coefficients. This allows to quantify and feed back more information about the switched converter waveform, and can thus reduce the dependence on the system model. The suggested approach is evaluated in both simulation and experiment and it is shown to be less sensitive to plant/model mismatch than approaches from the literature.
