飞行控制软件的实时性测试

The Real-time Testing of Flight Control Software

飞行控制软件是典型的实时嵌入式软件,必须满足时间约束条件。因此,对飞行控制软件的实时性进行测试很有必要。本文中飞行控制软件采用Host-Target测试模式,进行半实物仿真实验。在选取实时性度量指标的基础上,制定合适的测试用例生成策略,手动生成测试用例,利用插桩方法,对飞控软件进行实时性测试,并进行了仿真实验。实验结果表明该方法可以有效地解决飞控软件的实时性测试问题。

Flight control software（FCS） is one of representative real-time embedded softwares, which must meet time restriction. So it is indispensable to test the real-time of FCS. In this paper, FCS adopts Host-Target test mode and achieves Hardware-In-the-Loop （HIL） simulation experiment. On the basis of real-time index choosing, appropriate test case generation strategy developped and generated by hand, in use of instrumentation method, we experiment and simulink real -time testing to FCS. The result indicates this method can solute availably the real-time testing question of FCS.
