Condition Monitoring of Fluid Power Systems: A Survey

The topic of condition monitoring has been an area of significant research in the last two decades. There are many reasons for the increased popularity of this research field. These reasons include the need to diagnose increasingly complex modern-day systems coupled with the continuous desire to provide better product reliability. Additionally, the dramatic improvement in digital computing speed and flexibility has enabled much of this technology to be feasibly implemented. The condition monitoring research area is quite diverse in both its applications and the approaches necessary for implementation. This paper will provide a survey of literature pertinent to condition monitoring applied to fluid power systems. In addition, some distinctions between various methodologies will be investigated.
