TLDR
In this article, the authors argue that the integration of optimal control synthesis and manual tuning in the quantitative feedback theory (QFT) design environment enables design of controllers with levels of performance that surpasses what can be achieved using only a single technique.About:

μ-synthesis for a compact disc player
M Maarten Steinbuch,Pieter J.M. Van Groos,Pieter J.M. Van Groos,G. Schootstra,Pepijn M. R. Wortelboer,Okko H. Bosgra +5 more
TL;DR: In this paper, the design and implementation of robust multivariable controllers for a compact disc mechanism is considered, with the objective of achieving good track-following and focusing performance in the presence of track disturbances, external mechanical shocks and structured norm-bounded plant uncertainty.

Generalized frequency weighted balanced reduction
P.M.R. Wortelboer,O.H. Bosgra +1 more
TL;DR: In this article, a generalization of the original frequency weighted balanced reduction and an extension of the frequency interval balanced reduction is presented. But the generalization does not address the scalar quadratic frequency functions, which are assigned in separate frequency intervals.

Robust feedback synthesis for margins at the plant input
TL;DR: The QFT for uncertain MIMO feedback systems is a tool to design the two degree-of-freedom of a feedback system that satisfies demands of robustness, performance, and gain and phase margin at the plant input for diagonal controllers.

A New Formulation of Multiple-Input Multiple-Output Quantitative Feedback Theory
Yongdong Zhao,Suhada Jayasuriya +1 more
TL;DR: The QFT robust performance problem in its entirety may be reduced to an H∞ problem by casting each specification as a frequency domain constraint on the nominal sensitivity function and the complementary sensitivity function as discussed by the authors.
