Abstract: The characteristics of transient heating control process of aerodynamic simulation experiments are complicated, transient, high non linearity and strong coupling, which make it difficult or impossible to get a mathematical model. By using fuzzy control method,many good qualities (such as robust, high adaptability on changing parameters and short transition process time) can be obtained. Based on the fuzzy control method, a transient aerodynamic heating simulation control system for missiles was established. It was demonstrated that quick dynamic control of aerodynamic simulation heating process according to the transient and continual change of heat flow on the surface of a flying missile body can be completed by using this control system.
