Robustness of full order and restricted structure optimal control systems

Grimble, M.J. (2004) Robustness of full order and restricted structure optimal control systems. International Journal of Systems Science, 35 (6). pp. 375-388. ISSN 0020-7721 (http://dx.doi.org/10.1080/00207720410001717389)

Abstract

A simple method for modifying and improving the robustness of LQG optimal controllers is considered. A sensitivity costing term is introduced into the cost index and a fictitious disturbance signal, which affects robustness margins, is discussed. The influence is somewhat different on full-order and restricted-structure designs, and this is explored. Finally, the effect of a coloured measurement noise model on the robustness of the solution is investigated.
