在典型可靠性分析模型及理论基础上,建立了运载火箭复杂容错控制系统可靠性分析模型,提出了行之有效的可靠性建模方法,并进行了算例分析。结果表明,该方法能够为复杂容错控制系统可靠性评估、确定合理的系统组成以及方案优化提供良好的支撑,可在控制系统工程设计中推广应用。
Based on the typical reliability analysis model and theory, the reliability analysis model of the complex rocket vehicle fault tolerant control system is established. The effective reliability modeling method is put forward and an example is given. The results show that this method can provide a good support for the reliability assessment of complex fault-tolerant control system, to determine a reasonable system composition and program optimization, and can be widely applied in control system engineering design.
