Vector control for a multi-phase system

A method for vector control of a multi-phase system, the method comprising:

• selecting, based on a hysteresis value, an angle of a current voltage reference, and an angle of a previous voltage reference, a first shifting pattern from a plurality of shifting patterns for controlling the multi-phase system;
• generating, based on the selection of the first shifting pattern and the current voltage reference, a first pulse modulated signal for a first phase of the multi-phase system and a second pulse modulated signal for a second phase of the multi-phase system;
• and
• controlling switching circuitry to generate, based on the first pulse modulated signal, a first phase signal for the first phase and to generate, based on the second pulse modulated signal, a second phase signal for the second phase.
