【摘要】：飞机的全静压系统是飞机的必备系统,其工作是否正常直接影响飞行安全,因此在维护过程中,对飞行器全静压系统的测试至关重要。本课题所设计的全静压测试器可以用在需要进行飞机进行全静压测试的内场维修和外场维修中,系统按照测试人员的操作指令,为飞机全静压系统分别提供相应的气压源,同时有自动泄露检测等常用功能。系统具备完整性和创新性,便于操作,能够实现对全静压系统的全自动测试,控制精度高,可以代替进口的高价设备,具备完全的自主知识产权,并实现了设备的自主维护,节约了民航领域相关环节的成本。本课题在分析控制系统的结构和要求的基础上,建立了系统的数学模型,针对气压控制系统设计了PID算法控制器,解决了小流量气压控制系统的控制问题;根据设备指标对执行机构和其它器件进行了选择,根据操作要求对整个系统的结构、硬件、软件进行了设计,完成了组装和调试工作;对研制完成的设备进行了实验验证,与仿真结果相互对比,表明系统达到了设计的最初目标。
[Abstract]:The total static pressure system of aircraft is an essential system for aircraft. Whether its work is normal or not directly affects flight safety. Therefore, in the maintenance process, it is very important to test the total static pressure system of aircraft. The total static pressure tester designed in this paper can be used in the internal field maintenance and the outside field maintenance which need the aircraft to carry out the full static pressure test. The system provides the corresponding air pressure source for the aircraft total static pressure system according to the operation instruction of the tester. At the same time has automatic leak detection and other common functions. The system has the advantages of integrity, innovation, easy operation, automatic test of the total static pressure system, high control precision, can replace the imported high price equipment, complete independent intellectual property rights, and realize the independent maintenance of the equipment. The cost of related links in civil aviation field is saved. On the basis of analyzing the structure and requirements of the control system, this paper establishes the mathematical model of the system, designs the PID algorithm controller for the pneumatic control system, and solves the control problem of the small flow pneumatic control system. According to the equipment index, the actuator and other devices are selected, the structure, hardware and software of the whole system are designed according to the operation requirements, and the assembly and debugging are completed. The experimental results are compared with the simulation results, and the results show that the system has reached the initial goal of the design.
