Hi there, I need to find out the three parameters of a pid thermal
regulator of an induction heating oven. Is the Ziegler-Nichols the
most usefull method to get Kp, Ki and Kd? How can I determin the
transfer function of the system?
Thanks,
Marco
ZN may not be the best, but I can't say what is till you define
'best".
ZN method includes the system test that allows you to determine the
coefficients, assuming they will let you play with the actual system
enough to complete the test without an operator having a heart attack.
Thanks everybody for asking me back, but I've got one more question.
Do anyone knows a brief and comprehensive explanation of the three
control parameters Kp, Ki and Kd? I need to get some rules like "if
you increase Kp the system will... because Kp does..." for each of
them, letting me understand their meaning and what happens tuning one
or another.
Thanks,
Marco
