Stability and Well-posedness of a Nonlinear Railway Track Model
M. Sajjad Edalatzadeh, Kirsten A. Morris
Railway tracks rest on a foundation known for exhibiting nonlinear viscoelastic behavior. Railway track deflections are modeled by a semilinear partial differential equation. This…
Zero Dynamics for Port-Hamiltonian Systems
Birgit Jacob, Kirsten A. Morris, Hans Zwart
The zero dynamics of infinite-dimensional systems can be difficult to characterize. The zero dynamics of boundary control systems are particularly problematic. In this paper the ze…
Efficient electrochemical model for lithium-ion cells
Sepideh Afshar, Kirsten Morris, Amir Khajepour
Lithium-ion batteries are used to store energy in electric vehicles. Physical models based on electro-chemistry accurately predict the cell dynamics, in particular the state of cha…
Landau-Lifshitz Equation with Affine Control
Amenda Chow, Kirsten A. Morris
The Landau-Lifshitz equation is a coupled set of nonlinear partial differential equations that describes the dynamics of magnetization in a ferromagnet. This equation has an infini…
Modeling and related results for current-actuated piezoelectric beams by including magnetic effects
Kirsten A. Morris, Ahmet Ozkan Ozer
Piezo-electric material can be controlled with current as the electrical variable, instead of voltage. The main purpose of this paper is to derive the governing equations for a cur…
