Multivariable robust controller design for a boiler system
TL;DR: This work designs a robust multivariable controller using H/sub /spl infin// loop-shaping techniques and reduces this controller to a multivariability PI controller, and shows that the designed controllers are superior in robustness and performance to the existing multiloop controller.

Dynamic modelling, validation and analysis of coal-fired subcritical power plant
Eni Oko,Meihong Wang +1 more
TL;DR: A detailed dynamic model of a 500 MWe coal-fired subcritical power plant was developed using gPROMS based on first principles and showed that implementing load changes through ramping introduces less process disturbances than step change.

Application of dynamic matrix control to a boiler-turbine system
TL;DR: In this article, the authors presented an application of dynamic matrix control (DMC) to a drum-type boiler-turbine system of a fossil power plant, and two possible kinds of step response models were investigated in designing the DMC, one is developed with the linearization of theoretical model and the other is developing with the process step-test data.

Some thoughts on the advanced control of electric power plants
N. W. Rees,C. X. Lu +1 more
TL;DR: This paper describes some of the advanced controllers that might be very effective in the industry, including many that are being offered to the industry by the control vendor companies, and tries to suggest how the situation might be improved.

Data-driven modelling and fuzzy multiple-model predictive control of oxygen content in coal-fired power plant
TL;DR: In this article, a data-driven method with fuzzy c-means clustering and subspace identification is used to identify the model parameters and then, model predictive control integrated with a fuzzy multiple-model was used to control the oxygen content tracking problem.

A decomposition of near-optimum regulators for systems with slow and fast modes
Joe H. Chow,Petar V. Kokotovic +1 more
TL;DR: In this article, conditions for complete separation of slow and fast regulator designs are formulated and a second order approximation of the optimal performance is achieved without the knowledge of the small singular perturbation parameter.

Design of industrial regulators. Integral feedback and feedforward control
H. W. Smith,Edward J. Davison +1 more
TL;DR: In this paper, a theory of control and observation for linear constant multivariable systems with constant disturbances is presented that leads to design methods for linear regulators of both integral feedback and feedforward types.

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.
