How does a PID controller regulate temperature?
Thread Content
Experts, please help me figure out how to adjust the PID parameters of this curve so that it can remain stable. The current PID is 3,8580,156
I can’t provide an exact PID value either. Here’s a mnemonic for the 4:1 attenuation method: to determine the optimal parameters, start by checking values in ascending order; first use the proportional term, then the integral term, and finally add the derivative term. If the curve oscillates frequently, increase the proportional gain; if the curve wanders around in large swings, reduce the proportional gain. If the curve takes a long time to return to its normal level, decrease the integration time. If the curve has long fluctuation cycles, extend the integration time further. If the oscillation frequency is high, first reduce the derivative term. If there is significant steady-state error and slow fluctuations, increase the derivative time. An ideal curve should have two peaks – one higher at the beginning and one lower at the end, with a 4:1 ratio.
This is an amplitude-modulated oscillation; you can adjust the gain and integration by using the formula mentioned above.
The smaller the proportion and integration, the stronger the effect; I think your integration time is too long. Integration is used to eliminate residual errors.
Okay, thank you. I’ll give it a try
If the amplitude, proportional, and integral effects are too strong, it is possible to reduce the proportional and integral values appropriately to observe changes in the curve; several adjustments can be made to achieve the desired result.
You can try it little by little; it’s just experience in working together
It was adjusted by an expert we hired; I can’t remember what software was used
