Bifurcation Analysis of a Rotating Arm with Saturated Hamiltonian Control Laws

The actuator saturation effects on the global state space structure of a rotating arm with a Hamiltonian control law are studied via bifurcation analysis. In addition to other well-known codimension-two bifurcation points, some saturation-induced "fan-like" bifurcation points are detected. The dynamical complexity found in this seemingly simple example is remarkable.
