Control of Decommissioned Satellites and Space Debris Using CubeSats with Ion Electrospray Engines
Felix Biertümpfel, Peter Seiler, Paulo Lozano +1
The emergence of the New Space era has led to a rapidly increasing number of satellites in Low Earth Orbit (LEO). Consequently, more stringent deorbiting requirements have recently…
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…
