Start by filtering your measured value, I'd recommend an exponential smoothing with smoothing factor close to 1 at first and then you lower it until your measured value starts making sense. Or if your sensor has it, configure it so it has a bigger integration time and the value becomes more stable. However internally the sensor does just the same kind of smoothing. Then if you don't know your process you can try to tune it with TIA (pretune and then fine tune) or apply the Ziegler Nichols method to tune it. |

hi, sorry,i did not understand your answer .. i m a beginner with PID what concretely should i do ? modify P value ? I value ? .. add a new function bloc to have the exponential smoothing ?! the sensor is smooth without regulation, its my output hwo make it non, stable , attached a screen of my LMN ( in % ) thanks |
