摘要
针对座舱功能试验压力控制系统参数调试不允许在飞机座舱上直接进行的问题,建立了包括气动减压阀阀芯构件动态特性与试验管道压力变化过程等因素在内的座舱功能试验压力控制系统模型,可使压力控制系统设计客观化、解析化.通过对系统模型进行线性化和拟合降阶,再根据降阶模型应用解析化方法,设计了座舱功能试验压力控制系统的比例、积分、微分(PID)控制器,并对设计结果进行了仿真验证.结果表明,解析化方法设计的PID控制器可以满足飞机座舱功能试验压力控制系统的技术要求.
Aiming at the problem that it is not allowed to debug pressure control system parameters of cabin function test directly in the airplane cabin,the model of pressure control system in cabin function test was built.The model contains the effects caused by the dynamic characteristics of pneumatic valve components and the pressure variation process of pipeline,which makes the design of the control system objective and analytical.The model linearization and model reduction were applied to design PID controller for pressure control system in the cabin function test.The simulation results of pressure control system show the PID controller obtained by analytical method can meet the technical requirements of airplane cabin function test.
