Current loop current motor driven by FOC, do first test, when orders 10000 IQ, continue the motor load, at this time can get the phase from the oscilloscope for peak 10 amperes wave current, DC bus current will also rise because of sustained loading, but turn degree of motor, DC bus current down to 5 amp instead, observe the machine is an IQ of 9000, close to the command value, but PI Vq almost fixed income, lead to the DC bus cannot rise,
Want when motor stalling, DC bus can maintain 15 amperes of current, have fixed Vq test values, can get 15 amperes of current value, but not from IQ PI calculation reaches the Vq, think where there is a problem? How to do to control DC bus current blocked?
