On reduction of redundant data in the quadratic optimal control formulation for linear systems with commensurate time-delays

The possibility of reducing redundant data in the quadratic optimal control formulation for systems with linear models and commensurate time delays is described. It is demonstrated that when the system model is transformed to certain canonical forms then some redundant data in the quadratic cost functional can also be eliminated. Such a reduction of redundant data can aid one in choosing the "weights" of the quadratic cost functional and can help to simplify the defining equations for optimal feedback control.
