Wang, Zenghui; Chen, Zengqiang; Sun, Qinglin; Yuan, Zhuzhi Survey of the development for quantitative feedback theory. (Chinese. English summary) Zbl 1187.93045 Control Theory Appl. 23, No. 3, 403-410 (2006). Summary: Quantitative Feedback Theory (QFT) is a robust control theory based on frequency domain. It can be used to control single variable linear/nonlinear and multivariable linear/nonlinear systems with high uncertainty. In this paper, the basic theory, designing process and characteristic of QFT are described. The development of QFT is then summarized in several fields; increasing performance, robust stability research, automatic design and its applications. Some theory results are also given. Finally, the future development is discussed.
