Abstract
A simple method of 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, that affects robustness margins, is discussed. The influence is somewhat different on full-order and restricted structure designs and this is explored.
