摘要
为提高控制器乃至发动机系统工作的可靠性,提出了基于双机热备控制器的冗余设计方案,通过对双机热备关键技术的研究,对技术难点进行攻关,提出了具体的解决措施,确保了双机的同步运行和主备机的可靠仲裁,从而构建了一个可靠的控制器系统,实现了双机热备控制器的自主研发技术储备,可以满足工程应用需要。
A controller is one of the core components of an aerospace engine system. In order to improve the reliability of the controller and aerospace engine system, a dual-processor of hot standby redundant design is used. The key components of the controller are dual-redundant design. The hot standby redundant key technology to ensure the synchronization of the dual-processor operation and reliable machine arbitration is presented. A reliable controller system to meet the needs of engineering applications is constructed.
