摘　　要：作为飞机环境控制系统的重要组成部分,气源系统稳定的出口压力和温度对下游座舱压调子系统、机翼防除冰子系统及空气循环子系统等子系统的稳定工作至关重要。在发动机复杂恶劣的运转环境及传统液态控温技术无法满足控温精度的情况下,在传统PID控制基础上,提出了一种基于温度/温度变化率为控制对象的PID算法。通过仿真验证和系统台架试验验证表明,当发动机引气温度或下游用气需求温度发生变化时,该算法完全能够满足气源系统对温度、压力控制的稳定性、快速性及准确性要求,为下游用气系统提供稳定的供气来源,进而为飞机其他环控子系统的温度压力控制提供了工程参考。As an important part of the environmental control system,the stable outlet pressure and temperature of the air supply system are very important to the stable work of the downstream cabin pressure control system,wing anti-deicing subsystem and air circulation subsystem.In the complex and harsh operating environment of the engine and the traditional liquid temperature control technology cannot meet the temperature control accuracy,this paper on the basis of the tradition PID control,designed a PID algorithm based on temperature/temperature change rate as the control object.Simulation verification and system bench test verification show that when the engine bleed air temperature or downstream gas demand temperature changes,the algorithm can fully meet the air supply system on temperature,pressure control stability,speed and accuracy then provide engineering reference for the temperature and pressure control of other aircraft environmental control subsystems.
