@@@@In view of the pressure control system of aircraft pneumatic accessories test stand has some characteristics, such as nonlinear, time-variation, and prone to parameters changes, etc. In this study, an adaptive fuzzy PID controller was designed to improve the traditional PID which has the shortcomings of hard to adjust parameters setting and poor adaptability. The tests prove that the controller can make the pressure control system have a strong robustness, reach a steady state in a short time, and have a high precision. Therefore, it can improve the test efficiency and save gas resource.
