An optimal design approach for tracking problems and its assessment against classical controllers
N. J. KRIKELIS, Evangelos G. Papadopoulos · International Journal of Control · 1982
A class of linear regulator problems, referred to as tracking problems, impose the requirements of zero steady state error, elimination of disturbance effects and immunity to system parameter changes. A controller design approach for this problem, using linear optimal control theory, is presented, and its advantages are outlined by comparison with previous modern and classical approaches.
