摘　　要：座舱盖加温加载试验台是验证飞机飞行时的气动加温和气动加载是否会引发座舱盖疲劳破坏的最有效途径之一,但在设计与搭建试验台的过程中,不可避免地会遇到座舱盖表面温度场滞后和超调等问题。在交流换热给座舱盖加温的背景下,对加温系统进行建模,分别给出串级PID调节器和加温控制系统的设计方案,并对控制效果进行分析。结果表明:本文设计的加温控制系统有效地解决了加温过程中温度场滞后及超调的问题,且灵敏度较高。The cockpit cover heating loading test-bed is one of the most effective ways to verify whether the aerodynamic heating and aerodynamic loading will lead to the fatigue failure of the cockpit cover,however,in the process of designing and building the test-bed,it is inevitable to encounter the problems such as the lag and overshoot of the surface temperature field of the canopy.Under the background of heating the cabin cover by AC heat exchange,the heating system is modeled,and the design schemes of cascade PID(Proportion Integration Differentiation)regulator and heating control system are given respectively,and the control effect is analyzed.The results show that the heating control system designed in this paper can effectively solve the problem of temperature field lag and overshoot in the heating process,and is of high sensitivity.
