To Do

  • Temperature sensor volatility remains a problem, rendering the PID D term unusable.
    • Implement a better smoothing function. Consider forward weighted moving average over significantly more than 10 terms.
    • Look at the run from 2024-09-03 to find out the period of the high temperature swings.
    • Look at the data from 2024-09-04 to find the noisiness at low temperature.

Notes

Run 1

  • Thermocouple response is very laggy.
  • Clock doesn't run when temperature is outside range.
  • Laggy thermocouple means temperature overshoots.
  • Rate throttle is aggressive, but necessary given laggy thermocouple.
  • Temperature reading may be a bit on the low side (actual is 5 - 10f higher), though tough to say because of lag.
