This paper proposes a systematic procedure for the selection of controller design points in a linearized gain scheduling control context. The pointwise gap metric is first used to cluster linear systems obtained over the nonlinear system's operating space into a relatively small number of sectors. For each sector a suitable controller design point is provided. Existence of a linear controller stabilizing all systems inside a sector is guaranteed as well. The design point density and the overall gain-scheduled controller can be further refined in a second phase to satisfy additional linear robustness and performance considerations. The procedure is tested on the pitch axis dynamics of a highly agile industrial missile.
