| 摘 要： | 高压除水环境控制系统是典型的多输入多输出(MIMO)复杂控制系统,各个变量之间存在很强的耦合关系.试飞证明,采用传统的PID控制方法不能很好的解决电子设备和座舱的冷却问题,最明显的就是电子设备舱的冷却效果不佳.因此,对现有的飞机环境控制系统(ECS)必须加以改进.通过仿真表明,采用输出反馈、静态解耦控制后的环境控制系统能够满足系统设计要求.

| Abstract: | Aircraft environmental control system(ECS) with high pressure water separation is a representative complex coupling control system of MIMO. Flight tests proved that the controlling means with conventional PID control could not refrigerate the electronic equipment and the cabin satisfactorily. An attempt was made to use the controlling means of output feedback and static decoupling to improve the actual aircraft ECS. Through computer simulation, it was demonstrated that the improved aircraft ECS can satisfy the system design demands. |
