Maximum Sampling Rate of PID Library

Projects General Guidance
1

I wish to use the PID Arduino library to create a PI controller with a sampling frequency of 100Khz. for a power factor correction boost converter.

Is this possible? Because i believe that maximum sampling time of arduino UNO is 10Khz? i heard somewhere it can reach to 100Khz.

in the code the sampling time is divided by 1000 so if sampling time is 1000, then it 1 sec.

So in this method, the sampling time would need to be set to .001 to get the 100Khz needed.

I feel having a decimal tho wouldn't work.

any help would be much appreciated.

void SetTunings(double Kp, double Ki, double Kd)
{
  double SampleTimeInSec = ((double)SampleTime)/1000;
   kp = Kp;
   ki = Ki * SampleTimeInSec;
   kd = Kd / SampleTimeInSec;
}
 
void SetSampleTime(int NewSampleTime)
{
   if (NewSampleTime > 0)
   {
      double ratio  = (double)NewSampleTime
                      / (double)SampleTime;
      ki *= ratio;
      kd /= ratio;
      SampleTime = (unsigned long)NewSampleTime;
   }
}
