装备故障可否在其运行中得到控制或自行消除？故障能否像人和动物的疾病一样可以“自愈”？在系统科学的指导下，移植现代医学“自主调理”治疗原理，包括免疫、防御、代偿、自修复和适应等，可以用来指导研究装备自愈原理及工程应用；重点研究了以故障预防和消除为目标的装备系统自愈调控原理，为研制出具有自愈功能的新一代装备提供科学依据。

Can mechanical faults be controlled and eliminated at machine's run-time? Can a machine heal itself, as a living person or animal? What can be done before shutting down and overhauling a machine? Under the guidance of the systemics theory，borrowing the idea of “self-recuperation” therapeutic methdology in modern medicinal science, e.g.，the knowledge about the mechanisms of immunity, protection, compensation, regeneration, adaptation, etc., with the fault prevention and self-healing as the goal, this paper focuses on the study of the fault self-recovery principle and its engineering application, i.e. Fault Self-recovery Engineering (FSE), which can provide theoretical basis in developing a new generation of self-healing machine.
