摘要

In this work we obtain the bond-graph representation of the vocal folds, to then obtain a port-Hamiltonian model. This model is based on the mechanical elements that represent the folds in the body cover model (BCM). The obtained port-Hamiltonian system is then discretised using a truncated Taylor series expansion. State and parameter estimation for this discretised model is then performed using a...
