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.
According to the cockpit function test pressure control system parameters debugging does not allow the aircraft cockpit directly on the issue, including the dynamic characteristics of the pneumatic valve components and test pipeline pressure change process and other factors, including cockpit function test pressure control system model , The design of pressure control system can be objectified and resolved.According to the linearization of the system model and the fitting of the reduced order, and then using the analytical method of the reduced order model, the proportional, integral and differential (PID) controller, and the simulation results of the design are validated.The results show that the PID controller designed by the analytical method can meet the technical requirements of the cockpit functional test pressure control system.
