Information

Field oriented control of asynchronous machine with time-average inverter. The first component of i_dq controls 'field', the second controls 'torque' at constant 'field'.

On-load steady-state start with torque-increase at 3 s, load-step 6 s and field-increase at 8 s.

See for example: 

  asm_ctrl.motor.tau_el
  asm_ctrl.motor.w_el
  asm_ctrl.motor.vPhasor
  asm_ctrl.motor.slip

Check vPhasor[1] < 1.
The time-average inverter produces a desired voltage proportional to vPhasor[1] even if vPhasor[1] > 1. For a time-resolved converter this corresponds to overmodulation.
