摘要:

为了对某涡扇发动机的核心控制部件——电子综合调节器进行研究,采用反向工程试验方法,建立一种能反映其工作原理、静态特性、动态特性的测试平台。该平台包括系统的组成、硬件设计、软件设计、数据采集与处理和系统的应用。根据此测试平台所测的数据编制的功能控制软件为进一步实现FADEC提供了有力的依据。另外也表明,该系统具有测试精度高、可靠性好、操作和维护方便等特点,可用于教学及科研过程中。

Abstract:

To study the performance characteristic of FADEC which is the most important components in the control system of a certain aeroengine, a test system reflecting the performance characteristic was established. In consequence the system outline, hardware , software and data acquisition and handling were discussed in detail. A control software can be concluded from the data based on the test system, which will be used in the FADEC system design. The simulation results show that the system has the advantages of being convenient and practical.
