The last chapter of this book is completely devoted to case studies for robust control. The first study continues the controller design for the lateral motion of an aircraft. We introduce different weightings as in Sect. 11.3.5 and obtain in this way a feedback loop with good damping properties without prestabilization. Then a block which models multidimensional input-multiplicative uncertainty is defined and, by applying the D-K iteration, a μ controller is synthesized which improves the robustness properties of the H ∞ controller as well as that of the LQ controller.
