I am interested in being guided to research work regarding automated tuning of PID controllers, especially in manufacturing plants for chemicals processing.
I recommend reading the books titled, "PID Control" by Johnson & Moradi, and "Autotuning of PID Controllers" by Cheng-Ching Yu. You also encouraged to learn about Åström & Hägglund autotuner because the identification and tuning mechanism are simple to understand. Please cover the basics of tuning PID loops before going after the advanced methods.
