Quantitative Feedback Theory (QFT) - Technique for Designing Multivariable Control Systems

摘要

The report satisfies the desire of practicing engineers and students to have one document that presents the Quantitative Feedback Theory (QFT) technique in a unified and logical manner. QFT is a unified theory using the available measurable states that is applied to the design of multiple-input, multiple-output (MIMQ) systems. It incorporates the multivariable nature of control systems plant uncertainties, wide variations versus time of plant parameters, robustness performance requirements, disturbance attention requirements, nonlinearaties in the plant model, and requirements for decoupled outputs.
