Reference (\(m_{ref}\)) and obtained (\(m_{out}\)) modulation indexes for both motors, mutual flux position (\(\Theta ^{dif}_{\psi }\)), and drive 1 angular speed (\(\omega _r\)). (a) the step change in mutual flux position from 0° to 120°; (b) the same variables shown for the mutual flux position 120°, (c) and 150°.
