Abstract :
This work proposes a simple, robust, efficient, and practicable method to automatically flag poor control performance. It uses only the run length of the actuating errors. Run length is defined as a state, and transitions between states are then modeled as a Markov chain. Transition probabilities are then compared with the control limits established from a user-defined period of good control.
