Technical Condition Monitoring Methods to Manage the Redundancy of Systems. Part I: Built-in Control and Partition into Classes

Abstract. Redundancy management of a technical system involves a monitoring procedure (control of the current state of its components) to reconfigure the system and improve the performance and autonomy of its application. This paper initiates a four-part survey of the state-of-the-art monitoring methods for redundancy management. Part I is mainly devoted to the analysis of voting schemes, fidelity rules, control codes, and program control, representing the most widespread monitoring methods in modern technical systems and built-in control. In addition, we examine long-known, albeit less common, monitoring methods: diagnosis with partition into classes and diagnosis based on algebraic invariants.

Keywords: technical condition monitoring, redundancy management, diagnosis, built-in control, control codes, partition into classes, algebraic invariants.
