Self-Healing Control: Review, Framework, and Prospect

The strong coupling between the components of a modern system and the increasing complexity of the system make the demand for intelligent control and maintenance of the system become higher and higher. Self-healing control extends the scope of intelligent control, which is an inevitable trend in the development of intelligence for automated systems. Self-healing technology has a wide range of applications, but its theoretical system has not yet been developed. First, the characteristics, functions, definitions, and theoretical framework of self-healing control are clarified by reviewing and summarizing the research status of self-healing technology and self-healing control in various fields. Second, the differences and relationships between self-healing control and control methods, such as fault-tolerant control and adaptive control, are analyzed and discussed. Finally, the development tendency of self-healing control is summarized. The research status of self-healing technology in related fields is analyzed and summarized, and the basic framework of self-healing control is extracted to lay the foundation for the theoretical exploration of self-healing control.
