TLDR
In this article, a design methodology for a class of multivariable feedback controllers for industrial processes is developed from the viewpoint of optimal linear regulator theory, which permits systematic design of multiivariable dynamic compensators to satisfy both transient and ultimate state performance requirements and has been applied to load-following control of fossil fueled power plants and power system load-frequency control.About:

Feedforward control to track the output of a forced model
J. Broussard,M. O'Brien +1 more
TL;DR: In this paper, a feed forward control technique is developed which enables a plant to perfectly track a model in the presence of a disturbance, assuming that both the model and the disturbance have time-varying inputs which are not known in advance.
Journal ArticleDOI
An optimal tracking approach to load-frequency control
TL;DR: In this paper, the authors take the view that the predominant problem of load frequency control (LFC) resides in the low frequency domain assosiated with bulk generation change and which is dominated by limited generation response capability.

The relationship between implicit model following and eigenvalue eigenvector placement
John R. Broussard,Paul W. Berry +1 more
TL;DR: In this article, a solution to implicit model following using the theory of feedforward matrices is presented, which is reformulated and shown to be equivalent to eigenvalue eigenvector placement.

Acoustics, stability, and compensation in boiling water reactor pressure control systems
Harry G. Kwatny,L. Fink +1 more
TL;DR: In this article, the effects of steam pipe acoustics on the control of steam pressure in boiling water reactors are analyzed. But the authors focus on the closed loop of a closed loop and do not consider how to account for the acoustical properties of the steam pipe.

Accommodation of disturbances in optimal control problems
TL;DR: In this paper, the problem of control in the face of unknown disturbances is studied from the optimization point of view, and a novel alternative approach is proposed which leads to physically realizable control laws which perform optimally in the presence of a broad class of unknown external disturbances.

Design and analysis of boiler-turbine-generator controls using optimal linear regulator theory
J. P. McDonald,Harry G. Kwatny +1 more
TL;DR: In this article, an approach to control system design based on optimal linear regulator theory and which recognizes the limitation of an imperfect model has been developed, which produces "integral-type" action which guarantees zero steady-state errors.

Multivariable PID estimation and control in systems with biased disturbances
TL;DR: In this paper, a solution is given to yield reset control action in multivariable control systems, where the controller consists of a state reconstructor and feedback from estimated process and environmental states, and if a special choice for the ''feedforward'' matrix operating on the estimated environmental states is made, integral, or reset, control action results.
