摘　　要：相比于军机,民机电传飞行控制系统对测试性提出更高要求,希望通过测试性建模手段,提前发现和检测出所有故障,并将故障隔离,进而提高飞机系统可测试性,降低产品寿命周期费用。分析了典型电传飞行控制系统的结构,构建了民机电传飞行控制系统的测试性设计和诊断策略,并以作动器控制电子为例,采用计算机辅助设计软件完成模型验证,其结果满足相关测试性指标要求。Compared to military aircraft, civil aircraft flight by wire （FBW） demands higher requirements for testability, hopes that through means of testability modeling to detect and isolate all faults early, impro-ving aircraft system testability, reducing the cost of the product life cycle. This paper analyzes the structure of FBW, builds civil aircraft FBW design for testability and diagnosis strategies, and actuator control electronics, for example, using computer-aided design software to complete model validation, results meet testability requirements.
