 Nov 9 asked Explanation of Chandrupatla's algorithm for root finding? Sep 20 comment Technique for predicting attractor capture in nonlinear differential equations? (quasi-pendulum equation) huh, I can't read the Li + Ruan article, but found these: ocw.mit.edu/courses/electrical-engineering-and-computer-science/… and phys.ttu.edu/~cmyles/Phys5306/Talks/2003/Driven_Dam_Pend.pdf Sep 20 comment Technique for predicting attractor capture in nonlinear differential equations? (quasi-pendulum equation) thanks, I'll take a look! Sep 12 answered Technique for predicting attractor capture in nonlinear differential equations?

(quasi-pendulum equation) edited tags Sep 11 comment Technique for predicting attractor capture in nonlinear differential equations? (quasi-pendulum equation) maybe a change of variable $u=\theta-x$? Since $x=vt$, $\dot{u} = \dot{\theta} - v$ and $\ddot{u} = \ddot{\theta}$ Sep 11 revised Technique for predicting attractor capture in nonlinear differential equations?

(quasi-pendulum equation) Oskar, that sounds exactly what I should do, but I have no idea how to go about doing it. :-( Sep 11 comment Technique for predicting attractor capture in nonlinear differential equations? (quasi-pendulum equation) You are correct that if $|v| > a/b$ then equilibrium is not possible. But I know that $v_{crit}$ is less than this, since the value is dependent on the initial values of $\theta$ and $\frac{d\theta}{dt}$.
