Design and simulation in fuzzy PID roaster temperature controller based on Smith pre-evaluation compensation

摘要

The temperature control system for the often-used roaster of ARP and its relative parameters were analyzed. Because of the characteristics of the controlled temperature such as non linear, timedelaying, uncertainty, the non linear fuzzy-PID control system based on smith pre-evaluation compensation has been designed and then simulated. It turns out that this kind of control strategy can improve the dynamic quality of anti-jamming performance for the temperature control system of roaster obviously.
