Abstract
The robustness characteristics of fast-sampling error-actuated digital set-point tracking PI controllers are established in the case of partially irregular linear multivariable plants. It is shown that the plant-parameter variations tolerable by such fast-sampling error-actuated digital controllers can be expressed very simply in terms of the step-response matrices of the nominal and actual plants. These general results are illustrated by examining the robustness characteristics of a fast-sampling error-actuated digital PI controller for the F-16 aircraft in case the flaperon and elevator suffer various losses in effectiveness.<>
