摘　　要：在飞机座舱压力控制优化建模中,针对座舱压力稳定性差,影响飞机的飞行安全,为提高座舱压力控制精度和稳定性,提出根据座舱压力控制系统原理建立反映特性的仿真系统。采用数字式座舱系统高精度压力控制,并建立排气活门、驱动装置和座舱压力模糊控制器模型。在MATLAB平台上进行实时仿真,实现数字式座舱压力控制系统特性的高精度分析。仿真结果表明,数字式飞机座舱压力控制系统稳定性和实时性能好,为座舱压力的稳定性控制优化提供了有效性的依据。In optimization modeling of aircraft cabin pressure control,the flight safety of the aircraft will influenced by low stability of cabin pressure. In order to improve cabin pressure control precision,a simulation system is proposed based on the principle of the cabin pressure control. The digital cabin system is built with high precision pressure control. The key parts model such as exhaust valve,actuating device and cabin pressure fuzzy controller is built. The characteristics of the digital cabin pressure control system are analyzed with high precision which is carried out on real time simulation on the MATLAB platform. The simulation results indicate that the digital aircraft cabin pressure control system has good real time performance,and can provide an effectiveness foundation for the stability optimization control of the cabin pressure.
