Power Supply Ripple Effects

My power supply (from a 3 phase generator) has an approximately ~13% voltage ripple on it at a frequency of around 9KHz. I plan on using that supply to drive a high pole count (22 poles) motor under FOC control at about 1500Hz.  Will the supply ripple cause trouble for the control loop?  If so, are there any ways to avoid this trouble?  Thanks.
