The Anatomy and Robustness of Discrete Proportional -Integral Adjustment and Its Application to Statistical Process Control
This paper explains the nature and importance of Proportional-Integral control and shows how it may be adapted to Statistical Process Control. The relation of this type of control to exponential smoothing, minimum mean ...
Choice of Repeated and Bounded Adjustment Schemes
An important problem in process adjustment using feedback is how often to sample the process and when and by how much to apply an adjustment. Minimum-cost feedback schemes based on simple, but practically interesting, ...
