Title:
MODEL PREDICTIVE CONTROL OF A CONVERTER BASED ON PULSE WIDTH MODULATED SWITCHING PATTERNS
Document Type and Number:
WIPO Patent Application WO/2019/137916
Kind Code:
A1
Abstract:
A method for controlling an electrical converter (12), the electrical converter (12) being adapted for converting a DC voltage (vdc) into a multi-phase voltage with at least two voltage levels, comprises: determining a modulating signal vector (u*abc) from a stator flux reference vector (ψ*s,
αβ); determining a switching pattern (54) from the modulating signal vector (u*abc ) via pulse width modulation, the switching pattern (54) comprising a sequence of switching transitions, wherein a switching transitions defines a switch position, at which a phase of the converter is switched from one voltage level to another voltage level, and a transition time instant at which the phase of the converter is switched; determining a stator flux error ( ψ*s,err,αβ) by subtracting the stator flux reference vector (ψ*s,αβ) from an estimated stator flux vector (ψs,αβ), which is estimated from measurements in the electrical converter (12); modifying the switching pattern (54) by moving transition time instants of switching transitions of the switching pattern (54), such that the stator flux error (ψs,err,αβ) is minimized; and applying at least a part of the modified switching pattern to the electrical converter (12).
