Abstract: Multivariable feedback control has been adapted for optimal control of the spatial power distribution in nuclear reactor cores. Two design techniques, based on the theory of automatic control, were developed: the State Variable Feedback (SVF) is an application of the linear optimal control theory, and the Multivariable Frequency Response (MFR) is based on a generalization of the traditional frequency response approach to control system design.
The two design methods lead to different structures for the control system, and both were studied in simulation. The objective of the paper is to show the benefits and problems related to the SVF and MFR techniques, when used to design a control system for a typical pressurized light water reactor core. The models and the design procedures are described and results from simulation experiments are presented.
The conclusion of the simulation experiments is that the two methods SVF and MFR are similar with respect to performance and computational requirements. However, during the design of this particular control system, the MFR method was easier to apply. The SVF control system includes a Kalman filter state estimator. The simulation experiments show that the state estimator converges sufficiently fast for use with the SVF control system.
