Name: QFT - Quantitative Feedback Theory
ID: m11109
Language: English (en)
Summary: Introduction to the QFT control method. QFT stands for Quantitative Feedback Theory, which emphasises the use of feedback in order to achieve adequate robust system performance tolerances despite the presence of plant and disturbances uncertainties. The robust control problem is formulated by a "quantitative means" for control design. The method is a very good introduction for students to become familiar with the idea of robust control.
