  In this paper we present control of infinite-dimensional systems by power
shaping methods, which have been used extensively for control of finite
dimensional systems. Towards achieving the results we work within the Brayton
Moser framework, by using the system of transmission line as an example and
derive passivity of the system with respect to the boundary voltages and
derivatives of current at the boundary. We then solve the stabilization problem
by interconnecting the system through a finite-dimensional controller and
generating Casimirs for the closed-loop system. Finally we explore possibility
of generating other alternate passive maps.
