—In this paper, we propose a dynamic high-gain scaling technique and solutions to coupled Lyapunov equations leading to results on state-feedback, output-feedback, and input-to-state stable (ISS) appended dynamics with nonzero gains from all states and input. The observer and controller designs have a dual architecture and utilize a single dynamic scaling.(More)
— We propose a six degree-of-freedom multi-body approach for modeling and simulation of Biologically-inspired (or Biomimetic) Autonomous Underwater Vehicles (BAUVs), i.e., artificial fish. The proposed approach is based on considering the BAUV as comprised of multiple rigid bodies interlinked through joints; the external force and torque on each rigid body(More)
—We propose a global high-gain scaling-based state-feedback controller for a general class of nonlinear systems containing uncertain functions of all the states and the control input as long as polynomial bounds on ratios of some uncertain system terms are available. The design is based on a high gain scaling involving appropriate powers of a high gain(More)
