摘要
为了满足航空动力装置电子控制器高可靠性的要求,本文设计了双通道电子控制器框架。在该框架下,通过周期任务冗余调度策略和基于健康位向量的通道健康监控方法,进一步提高余度系统的容错能力,在工程实践中具有较好的通用性。
In order to meet the high reliability requirements of electronic engine control, this paper designs a dual-channelelectronic engine control framework. Under this framework, the redundanttask scheduling strategy and the health bit vector based channel health monitoring method are used to further improve the redundancy system’s fault tolerance, which have good versatility in engineering practice.
