Insensitive H∞ Dynamic Output Feedback Control
Coefficient sensitivity analysis is used widely to investigate the effects of coefficient change on the solution of mathematical models [124]. Therefore, coefficient sensitivity analysis is a powerful method for evaluating the effect of the controller/filter coefficient variations on the performance of the systems. In recent years, strictly convex conditions have been developed for the problem of insensitive H∞ filter design by the authors [48, 146]. However, the problem of designing insensitive controllers with respect to multiplicative/additive controller coefficient variations is an non-deterministic polynomial (NP) optimization problem which is more difficult than the ...
