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.
