摘　　要：为解决某型涡扇发动机模拟式综合电子调节器普遍存在的使用寿命与发动机使用寿命不相匹配、监控水平不高、虚警不断等问题,以该型综合调节器为研究对象,完成了该型发动机数字式综合电子调节器的软、硬件系统设计。为了提高系统的可靠性,调节器内部设计了双余度硬件系统,并由系统的切换电路选择工作正常的硬件参与工作。工作过程中控制系统采用热备份的工作状态,并接收主控通道的工作信息,使备份通道始终跟随主控通道,从而保证控制系统平稳转换。最后对所设计的数字式综合电子调节器进行了试验,试验结果表明所设计的数字式综合电子调节器合理可靠并满足实际使用中的需求。The analog controller of a certain turbofan engine generally exisits the defects, in practice, such as that it doesnt match the engine in life - span, is poor in monitoring faults, gives the wrong alarm and so on. In order to solve these problems, taking the Digital Electronic Controller （DEC） as a studying object, we designed the hardware and software structure of the DEC. And also we designed two hardware systems to enhance the reliability of the DEC. The two hardware systems worked at the same time and the backup system received the main system＇s information every moment, thus keeping the switch process stable. Finally the experiment result of the DEC is given. The result indicates that the research and argumentation for the design of the DEC is reliable and reasonable.
