| 摘 要： | 为了提高微机控制发动机的可靠性,在航空发动机(或陆用航机)上,一般采用双微机系统。对于此类系统,一种情况是:两台微机处于同等重要地位,它们都执行同一套控制算法,通过加权仲裁后,输出信号,控制执行机构;另一种情况是,两台微机,一台作为主机,另一台作为辅机,正常时主机参与控制,辅机仅做故障检测,一旦主机发生故障,辅机接替主机,投入工作,本文对后一种情况的双机系统进行了研究,

| Abstract: | Communication and trouble-selfdetection of microcomputers in dual-computer system of aeroengine digital control are considered,and exchange operation between two microcomputers is discussed emphatically .The simulation tests of the exchange operation in dual-computer engine speed control system have been performed. The results of the tests are satisfactory. |
