THE SINGULARITY PROBLEM IN FINAL VALUE CONTROL,
Abstract
Final value control of linear plants is discussed. An expression for the closed-loop fundamental matrix is presented in terms of the open-loop transition matrix. It is shown that for scalar minimum-energy final value control the singularities in the feedback loops are inversely proportional to the order of the derivative being fed back; that is, the position loop has an nth order singularity, the velocity loop an (n-1)th order singularity, etc. A partially-closed-loop control is developed that allows the highest-order feedback singularity to be set between n and zero and the results are illustrated by examples.
