Method to Compute Pointing Displacement, Smear, and Jitter Covariances for Optical Payloads
Peter Seiler, Mark E. Pittelkau, Felix Biertümpfel
This paper presents a method to assess the pointing and image motion performance of optical payloads in the presence of image displacement (shift), smear, and jitter. The method as…

Robust Time-Varying Control Barrier Functions with Sector-Bounded Nonlinearities
Felix Biertümpfel, Jungbae Chun, Peter Seiler
This paper presents a novel approach for ensuring safe operation of systems subject to input nonlinearities and time-varying safety constraints. We extend the time-varying barrier…

Control Synthesis Along Uncertain Trajectories Using Integral Quadratic Constraints
Felix Biertümpfel, Peter Seiler, Harald Pfifer
The paper presents a novel approach to synthesize robust controllers for nonlinear systems along perturbed trajectories. The approach linearizes the system with respect to a refere…
