Abstract:

This paper presents a sensorless explicit model predictive control scheme for the DC-DC boost converter. No direct inductor current measurement is needed as the coil current is derived either via a static approximation or, for improved accuracy, through an extended Kalman filter. The estimate is used in the chosen optimal control problem formulation which yields the optimal input by intrinsically accounting for duty cycle and current constraints. The optimization problem is explicitly pre-solved off-line so that the on-line effort is reduced to a simple search in the resulting look-up table. No on-line optimization is required, greatly facilitating physical implementation and allowing for experimental validation on an integrated DC-DC converter through a fixed-point DSP.
