Controller performance monitoring control

A change in approach is clearly necessary in order that the full benefit of integrated plant condition management and control can be recognized and exploited. Improved control and enhanced performance monitoring will enable shutdown intervals to be extended without increasing the risk of premature or unexpected failure. In turn, this will increase the confidence of operations, inspection and management personnel in the effectiveness of unified plant administration.

Once service delivery has begun, the control process goes into action. A goal is to make the performance monitoring, evaluation, and feedback activities routine. Intensive monitoring of the quality of initial service encounters provides important feedback on problems that need to be addressed.

A support program to maintain validation shonld be identified. It should include procedures for change control, maintenance and calibration, secnrity practices, contingency planning, operating procedures, training, performance monitoring, and periodic review. Operation and maintenance is discussed further in Chapter 12. 

The BMS and similar systems integrated into the EMS architecture provide control and performance monitoring functionality to ensnre that performance criteria are met and performance deviations detected. Functional performance deviations will inevitably affect prodnct quality and... 

Maintenance history is an essential component of GxP compliance. Work instructions and SOPs controlling maintenance operations should ensure that the maintenance engineer records aU performance measures, observations, and maintenance tasks in a consistent manner with calibration records, for example, containing calibration parameters, with calibration procedure, reference to calibration equipment, name of engineer, date of calibration, next due date, etc. Where automated condition and performance monitoring is employed, the integrity of the recorded data is obviously a GxP issue.

Nowadays, for reasons of safety and performance, monitoring and supervision have an important role in process control. The complexity and the size of industrial systems induce an increasing number of process variables and make difficult the work of operators. In this context, a computer aided decision-making tool seems to be wise. Nevertheless the implementation of fault detection and diagnosis for stochastic system remains a challenging task. Various methods have been proposed in different industrial contexts (Venkatasubramanian et al., 2003). 

There should be written procedures for performance monitoring, change control, programme and data security, calibration and maintenance, persotmel training, emergency recovery and periodic re-evaluation. 

After installation of the system it should be qualified. The extent of the qualification should depend on the complexity of the system. The system should be evaluated and performance qualification, change control, maintenance and calibration, security, contingency planning, SOPs, training, performance monitoring and periodic re-evaluation should be addressed. 

When a failure occurs during operation, the cause can be attributed not only to the process equipment, or the sensor network but also to the controller. Controller performance monitoring (CPM), considered as a subset of plantwide process monitoring and diagnosis activities, deserves a separate discussion. Thus, Chapter 9 provides an overview of controller performance monitoring tools and offers a case study to illustrate the key concepts.
