Description

一种大型飞机座舱供气温度目标计算方法
技术领域
本发明涉及大型飞机座舱温度控制领域。
背景技术
大型飞机环境控制系统具有系统综合性高、控制精度高和自动化程度高等特点,系统引气的温度和压力大范围变化,冲压空气状态瞬态变化,座舱的动态变化等因数会引起座舱温度的非线性变化,对座舱温度控制系统提出很高的要求。
发明内容
本发明的目的是:
本发明提供一种大型飞机座舱供气温度目标计算方法,主要针对飞机座舱容量较大的飞机座舱环境温度控制。
本发明的技术方案是:
一种大型飞机座舱供气温度目标计算方法,包括:
步骤1、通过控制器采集传感器输出的座舱实际温度,通过控制器采集面板输出的座舱设定温度,计算座舱实际温度与座舱设定温度之间的控制误差ΔT;
步骤2、计算供气温度补偿项Td,计算公式为:
f(ΔT)为积分函数,t为时间;
f ( &Delta;T ) = &lambda; ( &Delta;T &GreaterEqual; 5 ) &lambda; &times; &Delta;T &divide; 5 ( - 5 < &Delta;T < 5 ) - &lambda; ( &Delta;T &le; - 5 ) , λ为积分系数;
步骤3、计算座舱供气温度目标值,计算公式为:
T SET _ P = T SET + &mu; &times; &Delta;T + T d ( - m < T SET _ P < n ) T SET _ P = - m ( T SET _ P &le; - m ) T SET _ P = n ( T SET _ P &GreaterEqual; n )
式中,TSET_P为座舱供气目标温度,TSET为座舱设定温度,n为座舱允许最高供气温度,-m为座舱允许最低供气温度,μ为供气温度调整系数。
本发明的优点是:
在座舱温度控制过程中,系统控制不需要检测系统引气的温度和压力、冲压空气状态、座舱热载荷等影响座舱温度控制的相关因素状态,而是通过控制误差计算座舱供气温度,计算方法简单,提高座舱温度控制的响应速度和控制精度,保证座舱温度控制的稳定性。
附图说明
图1为本发明流程图。
具体实施方式
实施例1如图1所示:
步骤1:
通过控制器采集传感器输出的座舱实际温度,通过控制器采集面板输出的座舱设定温度,计算座舱实际温度与座舱设定温度之间的控制误差ΔT;
步骤2:
计算供气温度补偿项Td,供气温度补偿项用于补偿飞机飞行过程中舱内载荷变化、飞行状态变化等引起的舱温控制误差,计算过程需确定Td上下限值,一般取-20到40。
f(ΔT)为积分函数,t为时间;
f ( &Delta;T ) = &lambda; ( &Delta;T &GreaterEqual; 5 ) &lambda; &times; &Delta;T &divide; 5 ( - 5 < &Delta;T < 5 ) - &lambda; ( &Delta;T &le; - 5 ) , λ为积分系数,根据座舱温度惯性特点确定。
步骤3:
座舱供气温度目标值算法设计计算公式为:
T SET _ P = T SET + &mu; &times; &Delta;T + T d ( - m < T SET _ P < n ) T SET _ P = - m ( T SET _ P &le; - m ) T SET _ P = n ( T SET _ P &GreaterEqual; n )
式中,TSET_P为座舱供气目标温度,TSET为座舱设定温度,n为座舱允许最高供气温度,-m为座舱允许最低供气温度,μ为供气温度调整系数,根据飞机飞行过程中热载荷确定,正确确定供气温度调整系数能缩短温度控制的响应时间,提高温度控制稳定性。
本发明所设计的系统控制误差积分目标值控制算法在飞行状态、飞行环境、载荷变化情况下能根据系统控制误差自动调整管路供气温度的大小以满足系统座舱温度控制精度要求,并成功运用于某大型飞机座舱温度控制系统。
