Lyapunov Constructions for System Interconnections Arising from Adaptation in Some Optimization Methods
Qixu Wang, Patrick McNamee, Zahra Nili Ahmadabadi +1
Interconnected systems have been widely studied, with a focus on interconnected systems whose subsystems are solely input-to-state stable (ISS) or passive systems. The focus of thi…

Servos for Local Map Exploration Onboard Nonholonomic Vehicles for Extremum Seeking
Dylan James-Kavanaugh, Patrick McNamee, Qixu Wang +1
Extremum seeking control (ESC) often employs perturbation-based estimates of derivatives for some sensor field or cost function. These estimates are generally obtained by simply mu…
