Designing controllers with predefined convergence-time bound using bounded time-varying gains
Rodrigo Aldana-López, Richard Seeber, Hernan Haimovich +1
Recently, there has been a great deal of attention in a class of controllers based on time-varying gains, called prescribed-time controllers, that steer the system's state to the o…

Worst-case error bounds for the super-twisting differentiator in presence of measurement noise
Richard Seeber
The super-twisting differentiator, also known as the first-order robust exact differentiator, is a well known sliding mode differentiator. In the absence of measurement noise, it a…

Generalized Filippov solutions for systems with prescribed-time convergence
Richard Seeber
Dynamical systems with prescribed-time convergence sometimes feature a right-hand side exhibiting a singularity at the prescribed convergence time instant. In an open neighborhood…
