Analysis and funnel control for nonlinear drill strings
Thomas Berger, Thavamani Govindaraj, Pushya Mitra +1
We study the output tracking problem for a vertically driven drill string system described by a nonlinear boundary-coupled PDE-ODE model. Solvability analysis of the drill string m…

Funnel control for passive infinite-dimensional systems
Thavamani Govindaraj, Anthony Hastir, Lassi Paunonen +1
We consider funnel control for linear infinite-dimensional systems that are impedance passive, meaning that they satisfy an energy balance in which the stored energy equals the squ…

Output Regulation for Impedance Passive Systems with Input Saturation
Thavamani Govindaraj, Lassi Paunonen
We consider output tracking and disturbance rejection for abstract infinite-dimensional systems with input saturation. We solve the control problem using a control law which consis…
