Hogan’s problem | Faculty of Civil Engineering, Rijeka, December 2013/January 2014

Hogan 1989MatLAB simulation to study influence of perturbations in initial conditions on the symmetry or asymmetry of the asymptotic response in phase plane (Hogan, 1989-1995):

– Picture 2: MatLAB prediction for inital angular displacement of 0,29°
Hogan_angular displacement 0.29 deg

– Picture 3: MatLAB prediction for inital angular displacement of 2,9°
Hogan_angular displacement 2.9 deg
