Thanks for your reply!
For the different temperature condition,I`ll get the different group Kp/Ki parameter of PI controller. at last how to confirm the final Kp/Ki parameter for all of temerature condition?I haven`t understand your clarification "Finally, you make feedback controller using PID block that is set so that control gains for each plant model can be input from the outside and be changed arbitrarily." would you please share more detailed information for it? thanks for your support.
