Hello,
I have high temperature laboratory furnace with resistance heating element 230V/16A switched with SSD, for temperature measurement i have thermocouple type B (optional type K). For more I have in electronics energy meter any Analog Devices and have real information o amount of energier poured into the furnace.
For control have any MCU ARM and will be use PID , but I have no real experience with PID , I don't know how to correctly tune PID controller constants.

Will you advise where to find an example of how such an example is solved?
I have access to matlab, but we never used its PID tuning tools.

You should have a look at the most used interactive methods for tuning PID controllers, namelly:

  • Ziegler–Nichols stepresponse method,
  • Chien–Hrones–Reswick method
  • Cohen–Coon method
...and choose the one with which you feel more confortable or give best results to your application.
