Paper Abstract

This paper describes a QFT/H design method which combines the Quantitative Feedback Theory (QFT) design concept and robust H optimal control technique via linear matrix inequality (LMI) convex optimization approach. The relationship between QFT and H robust control of tracking systems will be discussed. Based on our extensive experience with both H and QFT design approaches, it appears reasonable that by synthesizing both into a single design process and enjoying the benefits offered by each approach. The complexity of the robust control system design for space vehicle is decreased by combined QFT/H design technique. Furthermore the robust controller of command tracking system is designed by QFT/H method using the advantages of the two methods for space vehicle, and the results of design are validated through simulations.
