Methods for automatic control, observation, and optimization in mineral processing plants
TL;DR: In this paper, the authors describe a generalized control loop for controlling strongly disturbed, poorly modeled, and difficult to measure processes, such as those involved in the mineral processing industry, the peripheral tools of the control loop (fault detection and isolation system, data reconciliation procedure, observers, soft sensors, optimizers, model parameter tuners).

On-line fault diagnosis using the signed directed graph
Chung Chien Chang,Cheng Ching Yu +1 more
TL;DR: Improved diagnostic resolution can be achieved by imposing more stringent conditions at different states and by finding the dominant path of fault propagation using steady-state gains.
