Bidirectional branch and bound for controlled variable selection Part I : principles and minimum singular value criterion
The minimum singular value (MSV) rule is a useful tool for selecting controlled variables (CVs) from the available measurements. However, the application of the MSV rule to large-scale problems is difficult, as all feasible ...
Comparison of plant-wide oscillation detection methods
Plant-wide oscillations are common in many industrial processes. During the past few years, various methods have been proposed for the detection of plant-wide oscillations, including methods based on the autocorrelation ...
L1/Q approach for efficient computation of disturbance rejection measures for feedback control
This paper presents practical methods for computation of disturbance rejection measures, which are useful for assessing the dynamic operability of the process. Using L1 optimal control theory, we consider the cases ...
Bidirectional branch and bound for controlled variable selection Part II : exact local method for self-optimizing control
The selection of controlled variables (CVs) from available measurements through enumeration of all possible alternatives is computationally forbidding for large-dimensional problems. In Part I of this work, we proposed a ...
Achievable PID performance using sums of squares programming
In addition to process elements like time delay, the PID structure of the controller can pose fundamental limitations on the achievable control performance. A key difficulty in characterizing the limitations due to controller ...
μ-interaction measure for unstable systems
In this paper, we present a method for system stabilization through independent designs of the decentralized controller. The proposed method extends the practical applicability of the conventional μ interaction measure ...
