Actuators, Volume 8, Issue 3

September 2019 - 18 articles

Cover Story: This paper reviews artificial immune systems (AIS) that can be implemented to compensate for actuators that are in a fault state or operating abnormally. Eventually, all actuators will fail or wear out, and these faults must be managed if a system is to operate safely. AIS are inherently well-suited to these situations if the faults are treated as infections that must be combated. With the advent of distributed and cloud-based computing, these algorithms have begun to be feasible for diagnosing faulty actuators and then generating compensating controllers in near real-time. To encourage the application of AIS to these situations, this work presents the fundamental operating principles of AIS, their applications, and a brief case study on their applicability to fault compensation.
