This paper describes a fast-response gaseous temperature control system and presents a self-regulating fuzzy algorithm of PID control. To achieve a signal of the gas temperature with higher degree of accuracy and less response time, both of flux and power of heating are controlled in the algorithm. Firstly, construction and working principle of fast-response gaseous temperature control system is expounded. The combination of hermodynamics and pneumatics servo control theory is used as modeling of the system. Secondly, two kinds of control algorithms are applied to the system. The self-regulating fuzzy algorithm of PID controller is designed successful. The control schemas presented can improve the static and dynamic behavior of the system effectively.
