摘　　要：为模拟不同飞行状态下航空发动机的工作环境,设计了航空发动机地面试车台,该试车台能够通过管道供气的方式为航空发动机提供一定温度、压力的气体。介绍了包括进气系统及其控制系统在内的硬件系统架构的总体设计方案,以及模糊PID控制器的基本原理和设计思路。针对该试车台的加温加压进气系统设计了基于西门子PLC平台的控制系统,并在实际的试车工作中完成了验证与应用。其中,最后1级压力调节系统采用了模糊PID控制方法,在西门子PLC平台使用2种编程语言分别设计了模糊PID控制器模块,并对比了2种编程语言的设计效率和运行效果。分别通过计算机仿真和试车台试验及试车将模糊PID控制器的控制效果与传统PID控制器的进行对比,结果表明:模糊PID控制器的控制效果更优。In order to simulate the working environment of aeroengines under different flight conditions,an aeroengine ground testbed with the capability of supplying air to aeroengine at certain temperature and pressure through pipeline was designed.The framework the hardware system architecture including the intake system and its control system,as well as the fundamental principles and design concept of the fuzzy PID controller were introduced.The control system based on Siemens PLC platform was designed for the heating and pressurizing air intake system of the test-bed,and had been verified and put into operation during engine test.Fuzzy PID control method was adopted for the last stage pressure regulating system.Two programming languages were used to design the fuzzy PID controller modules on the Siemens PLC platform,and the design efficiency and operation performance of the two programming languages were compared.The control performance of fuzzy PID controller was compared with that of traditional PID controller through computer simulation,commissioning and engine test respectively.The results show that the fuzzy PID controller has better performance.
