In many mills, the ratio of control assets to engineers is greater than 300 to 1, which often means a complaint-driven or failure-based maintenance model is the norm. Due to this work overload, many control issues are seen as tuning related and are often addressed in this manor or
overlooked completely.
This paper presents an overview of a condition based maintenance approach to control performance monitoring. This approach is looking at the three fundamental aspects of asset optimization:
• Utilization
• Performance
• Sustainability
A case study with industrial results is presented to illustrate the concepts and benefits of continuous monitoring and condition-based maintenance.
