Numerical Treatment of Non-Linear singular pertubation problems
… of some novel numerical methods for non-linear singular pertubations problems (NSPPs). It provide a survey of asymptotic and numerical methods for some NSPPs in the past decade. By considering two test problems, rigorous asymptotic analysis is carried out. Based on this analysis, suitable …

Modeling, estimation and control for serial flexible robot arms
… tracking for flexible manipulator arms. A singular pertubation based controller is presented to actively damp out the vibrations in the arm. A test bed that provided verification of the claims made in this dissertation was designed and constructed. The test bed has 3 actuators and 2 …

Convergence Rates of Gradient Descent-ascent Dynamics under Computation Constraints in Solving Min-max Optimization
… GDA under delayed gradients. We utilize the singular perturbation approach to obtain convergence rates in two non-convex settings of the objective function, namely, the two-sided and one-sided Polyak - Lojasiewicz (PL) conditions, by designing a coupling Lyapunov function to capture the …

Defektkorrekturverfahren für singulär gestörte Randwertaufgaben
Wir untersuchen ein Defektkorrekturverfahren, das ein einfaches Upwind-Differenzenverfahren erster Ordnung mit einem zentralen Differenzenverfahren kombiniert, für ein- und zweidimensionale singulär gestörte Konvektions-Diffusions-Probleme auf einer Klasse von Shishkin-Typ-Gittern. Im …
