Brief Analytical PID parameter expressions for higher order systems
Alf J. Isaksson,Stefan F. Graebe +1 more
TL;DR: This paper proposes a technique to derive analytical PID expressions for higher than second-order systems, analyses its properties, demonstrates computational simplicity and shows that its performance is comparable to known numerical techniques.

Closed Loop Performance Monitoring in the Presence of System Changes and Disturbances
Fredrik Gustafsson,Stefan F. Graebe +1 more
- 01 Jan 1995
TL;DR: A novel performance measure is introduced that allows feasible application of a standard CUSUM change detector and includes explicit results on the probability of mistaking a disturbance for a system change.

Closed-Loop Performance Monitoring in the Presence of System Changes and Disturbances
TL;DR: In this article, a performance measure that allows feasible application of a standard CUSUM change detector was proposed. But the performance measure was not evaluated on a DC motor and the risk of mistaking a disturbance for a system change was not considered.

Brief Slow stable open-loop poles: to cancel or not to cancel
TL;DR: This paper considers control loops with integral action and shows that shifting slow stable real poles, rather than cancelling them, increases the l"1, H"~, and the point-wise in frequency norms of the complementary sensitivity.
