Variations of the Poincaré Map
Nogueira, in 1995, presented a study of the Poincaré map and the related ParryDaniels map. In this note some variants of this algorithm are presented which seem to have quite different ergodic behavior.
متن کاملDiscretization of Poincaré map
We analytically study the relationship between the Poincaré map and its one step discretization. Error estimates are established depending basically on the right hand side function of the investigated ODE and the given numerical scheme. Our basic tool is a parametric version of a Newton–Kantorovich type methods. As an application, in a neighborhood of a non-degenerate periodic solution a new ty...
متن کاملNumerical Construction of the Poincaré Map , with Application to Accelerators ∗
We show how to construct a symplectic approximation to the Poincaré map, using data from a symplectic integrator. We illustrate by producing a full-turn map for a realistic model of the Large Hadron Collider. Mapping of one turn is typically faster by a factor of 60 than direct integration. This allows one to follow orbits over times comparable to the required storage time of the beam, on a wor...
متن کاملLyapunov-based versus Poincaré map analysis of the rimless wheel
Hybrids systems are combinations of continuous and discrete systems. The bouncing ball is an extensively studied hybrid system, for which many solid Lyapunov-based tools are now available. Toward applying these tools to walking robots, where a hybrid dynamical system framework is also a natural fit, the rimless wheel provides a salient dynamic model because it shares commonalities with both bou...
متن کاملThe Poincaré Map of Randomly Perturbed Periodic Motion
A system of autonomous differential equations with a stable limit cycle and perturbed by small white noise is analyzed in this work. In the vicinity of the limit cycle of the unperturbed deterministic system, we define, construct, and analyze the Poincare map of the randomly perturbed periodic motion. We show that the time of the first exit from a small neighborhood of the fixed point of the ma...
