Bm. Maschke et al., AN INTRINSIC HAMILTONIAN-FORMULATION OF THE DYNAMICS OF LC-CIRCUITS, IEEE transactions on circuits and systems. 1, Fundamental theory andapplications, 42(2), 1995, pp. 73-82
First, the dynamics of LC-circuits are formulated as a Hamiltonian sys
tem defined with respect to a Poisson bracket which may be degenerate,
i.e., nonsymplectic. This Poisson bracket is deduced from the network
graph of the circuit and captures the dynamic invariants due to Kirch
hoff's laws. Second, the antisymmetric relations defining the Poisson
bracket are realized as a physical network using the gyrator element a
nd partially dualizing the network graph constraints. From the network
realization of the Poisson bracket, the reduced standard Hamiltonian
system as well as the realization of the embedding standard Hamiltonia
n system are deduced.
