综合数字控制技术在飞机环境控制系统的应用

Integrated Digital Control of Aircraft Environmental Control System

提出了一套新的综合数字控制硬件和软件解决方案应用于飞机环境控制系统中,以某先进战斗机环境控制系统为例先后进行了计算机仿真设计和原理性验证试验。结果表明,采用模糊控制方法的综合数字控制系统改善了原PID控制系统的性能,具有响应快、稳态精度高等特点,达到了飞机功能子系统的总体设计要求。

A new project of aircraft environmental control system for integrated digital control with hardware and software was proposed. The feasibility was validated in principle by ground test of an advanced air fighter ECS after computer simulation design. The new integrated digital control system with fuzzy control and the old PID control methods were compared in ground test. Fuzzy control method has fast response and good steady precision for aircraft ECS real time control. It is demonstrated that the improved actual aircraft ECS can satisfy the design demands of aircraft function subsystem.
