CCBII制动系统是一个复杂的非线性系统，可能出现孤立故障和多分量耦合故障，故障诊断是CCBII制动系统的关键问题。提出了一种基于奇偶空间的CCBII制动系统故障诊断方法。首先，根据CCBII制动系统的三个功能模块，运用气液两相流理论建立了数学模型。然后，为系统的各个输出设计奇偶向量和阈值函数，以识别更多的系统故障。根据系统的功能和内部结构，根据输出与故障之间的因果关系建立故障特征矩阵。最后，通过将观测到的系统输出与故障特征矩阵进行比较，实现故障检测与隔离。仿真结果表明，该方法是完全可行和有效的。
Fault diagnosis is a key issue of the CCBII (computer controlled brake II) braking system, because the CCBII braking system is very complicated and nonlinear, which may exhibit isolated and multi-component coupled faults. A parity space-based method was proposed for fault diagnosis of CCBII braking systems. Firstly, the mathematical models were established according to three function modules of CCBII braking systems where the air fluid theory was utilized. Then, parity vector and threshold function were designed for each output of the system so as to identify more system faults. Fault character matrix was built based on the causal relationship between the output and the fault according to the system function and internal structure. Finally, fault detection and isolation can be realized by the comparison of the observed system output and the fault character matrix. Simulation results show that the proposed method is entirely feasible and effective.
