An LFT (Linear Fractional Tranformation) design technique for self-scheduled controller synthesis is considered. Deriving a feedback gain in LFT form can be straightforward because most operations relative to matrices can be applied to LFT objects. Most computations can be performed off-line in the LFT case. The LFT-based approach presented here assumes that the parameter variations are sufficiently slow so that their speed of variation can be ignored (LTT, i.e. Linear Time Invariant approach). In the paper, some adaptations required in the LFT case are proposed. The method is applied to the design problem for a pitch axis control law for a missile flying in the vertical plane.
