Periodic fixed-points and their algebraic characteristics in discrete-time Lur'e feedback systems
Kang Tong, Christian Grussler, Michelle S. Chong
We study the problem of identifying nontrivial, i.e., nonzero, periodic fixed-points in discrete-time Lur'e feedback systems. Using the circulant matrix constructed from the transf…

Nonconvex Obstacle Avoidance using Efficient Sampling-Based Distance Functions
Paul Lutkus, Michelle S. Chong, Lars Lindemann
We consider nonconvex obstacle avoidance where a robot described by nonlinear dynamics and a nonconvex shape has to avoid nonconvex obstacles. Obstacle avoidance is a fundamental p…

Self-sustained oscillations in discrete-time relay feedback systems
Kang Tong, Christian Grussler, Michelle S. Chong
We study the problem of determining self-sustained oscillations in discrete-time linear time-invariant relay feedback systems. Concretely, we are interested in predicting when such…
