Abstract
Computational bifurcation analysis of multiparameter dynamical systems has been reported. Bifurcation methods have been widely used, to study nonlinear phenomena in aircraft flight dynamics. A bifurcation analysis must begin by computing all equilibrium and periodic solutions of that system along with information about the stability of these solutions. The bifurcation analysis of a multiparameter dynamical system involves solving a series of one-parameter problems of various forms. It is possible to capture multiple bifurcation points with a single computation, and this is illustrated with an example of a five-state, three-parameter dynamical system from aircraft flight dynamics. The key to our approach is to recognize that multiple bifurcations in the state-parameter space may be captured by a single computation solving. There is scope for devising better and more rigorous algorithms to arrive at the parameter constraint function, which forms the underpinning of the approach.
