Abstract : This report brings the Quantitative Feedback Theory (QFT) material up to the state-of-the-art level and aims to provide students and practicing engineers a document that presents QFT in a unified and logical manner and which addresses the real-world control problems. QFT is a unified theory using the available measurable states that is applied to the design of multiple-input multiple-output (MIMO) systems. It incorporates the multivariable nature of control systems' structured plant uncertainties, variation, robustness performance requirements, cross-coupling and external disturbance attenuation requirements, nonlinearities in the plant model, and requirements for decoupled outputs. The document also presents the fundamentals of system identification and discusses the vital MIMO QFT CAD package. (KAR) P.3
