Monitoring and Fault Detection for an HVAC Control System
A controller performance index developed by Desborough and Harris (1992) is proposed as a fault detection technique for the online monitoring of feedback control systems. An important theoretical advantage of this approach is that the performance index can distinguish between process variability due to external sources (e.g., load or setpoint changes) and variabililty due to a significant change in the feedback loop. The feasibility of the new approach is demonstrated via a simulation study for an air duct heating coil.
