7.3.11.3 Current PI Control
The MCF8316A has two PI controllers, one each for Id and Iq to control flux and torque separately. Kp and Ki coefficients are the same for both PI controllers and are configured through CURR_LOOP_KP and CURR_LOOP_KI. The outputs of the current control loops are used to generate voltage signals Vd and Vq to be applied to the motor. The outputs of the current loops are clamped to supply voltage VM. Id current PI loop is executed first and output of Id current PI loop Vd is checked for saturation. When the output of the current loop saturates, the integration is disabled to prevent integral wind-up.
