When designing helicopter IFPC (integrated flight/propulsion control) system with H ∞ theory, its robustness performance depends on the very complicated to design matrices W 1 and W 3 . We now present a relatively simple method for their design. Section 2 gives the details of our relatively simple method for designing W 1 , the sensitivity weighting matrix, and W 3 , the complementary sensitivity weighting matrix. Our method is so simple that engineers can use the details in section 2 to design W 1 and W 3 without having to glance through section 1, in which H ∞ theory is briefly summarized. The simulation results in Fig. 4 show preliminarily that the helicopter IFPC system designed by our method is decoupled and possesses strong robustness.
