TLDR
In this article, a method for the design of constant gain optimal feedback control laws for discrete-time systems which reduce trajectory sensitivity to small system parameter variations and ensure the closed-loop eigenvalues at the prescribed locations is proposed.Abstract:
A method is proposed for the design of constant gain optimal feedback control laws for discrete-time systems which reduce trajectory sensitivity to small system parameter variations and ensure the closed-loop eigenvalues at the prescribed locations. The selected performance index is of standard linear regulator type, modified to include a quadratic sensitivity term. An efficient computational procedure based on direct cost oprimization using gradient type algorithm is also reported. A case study of a Boiling Water Reactor power plant has been presented to illustrate the application of the design procedure.read more

Optimal control of a boiling water nuclear reactor
TL;DR: In this article, the optimal control problem of a linearized model of a nuclear reactor is treated as a regulator problem and feedback control laws are derived to drive the system to steady state in the presence of disturbances.
