小卫星电源控制系统容错设计的故障注入法

小卫星电源控制系统容错设计采用人为故障注入法,使用仿真系统替代控制对象,制造硬件故障,进行硬件故障仿真。通过人为改变程序源代码或编译码注入故障,进行软件仿真。并以二次电源控制的容错设计为例,模拟电源控制器的各种硬软件故障,结果表明该方法能全面验证卫星在轨飞行时电源控制系统的容错能力和可靠性。

Fault Injection for Fault-Tolerant Design of Control System for Power Supply of Micro-Satellite

By the way that simulates or injects faults which occur in actual system; verify the design of micro-satellite fault-tolerant power control system. Instead of control object, emulation system is used to produce hardware fault. Software fault simulate is completed by intent change program source code or compile code. An example about fault-tolerant design of second power control system is given; by simulate the software and hardware fault of power control system, it is proved that this method can completely verify the fault-tolerant capability and reliability of fault-tolerant design of satellite power control system in orbit.
