This paper discusses the performance of the designed digital electro-pneumatic cabin pressure control system for a cabin pressure schedule of transport aircraft. For the purpose of this study,an experimental setup consisting of simulated hermetic cabin and altitude simulated chamber is configured for cabin pressure control system operation. A series of experimental tests are executed to evaluate the performance of cabin pressure control system. The parameters of proportional integration differentiation(PID) controller are optimized. In the optimization process,the variation regularity of the rate of cabin pressure change under various conditions is considered. An approach that makes the rate of cabin pressure change priority control based on the flight status model is proposed and verified experimentally. Experimental results show that the proposed approach can be adapted to the designed digital electro-pneumatic cabin pressure control system and that better cabin pressure schedule and rate of cabin pressure change can be obtained.
