Bifurcation tailoring is a novel control technique aimed at changing the entire bifurcation diagram of a given nonlinear system to some desired one. Bifurcation tailoring was successfully carried out on a second order nonlinear highly manoeuvrable aircraft model so as to control the angle of attack to an arbitrary prescribed bifurcation diagram under the variation of elevator. On-line feedforward scheduling was carried out using a Newton Flow method, and feedback stabilisation was provided by an adaptive control strategy known as the Minimal Control Synthesis (MCS).
