hi! my name is attila karsai. i am a phd candidate at the institute of mathematics of tu berlin funded by the german research foundation within subproject b03 of the trr154. the project concerns optimal control of port-hamiltonian systems. take a look at the project page to learn more!

research interests

• port-hamiltonian systems
• structured optimal control and turnpike properties
• structured discretization and model reduction for nonlinear port-hamiltonian systems
