Trajectory Anti-Aliasing on Guaranteed-Passive Simulation of Nonlinear Physical Systems
Résumé
This article is concerned with the accurate simulation of passive nonlinear dynamical systems with a particular attention paid on aliasing reduction in the pass-band. The approach is based on the combination of Port-Hamiltonian Systems, continuous-time state-space trajectories reconstruction and exact continuous-time anti-aliasing filter realization. The proposed framework is applied on a nonlinear LC oscillator circuit to study the effectiveness of the method.
