Exponential stabilization of driftless nonlinear control systems using homogeneous feedback by Robert T McLoskey( )
1 edition published in 1997 in Undetermined and held by 1 WorldCat member library worldwide
This paper focuses on the problem of exponential stabilization of controllable, driftless systems using time-varying, homogeneous feedback. The analysis is performed with respect to a homogeneous norm in a nonstandard dilation that is compatible with the algebraic structure of the control Lie algebra. It can be shown that any continuous, time-varying controller that achieves exponential stability relative to the Euclidean norm is necessarily non-Lipschitz. Despite these restrictions, we provide a set of constructive, sufficient conditions for extending smooth, asymptotic stabilizers to homogeneous, exponential stabilizers. The modified feedbacks are everywhere continuous, smooth away from the origin, and can be extended to a large class of systems with torque inputs. The feedback laws are applied to an experimental mobile robot and show significant improvement in convergence rate over smooth stabilizers
Converting smooth, time-varying, asymptotic stabilizer for driftless systems to homogeneous, exponential stabilizers by Richard M Murray( )

Control-Oriented Modeling and Feedback Compensation For a Thin-Film TiNi Actuator ( )
1 edition published in 2002 in English and held by 1 WorldCat member library worldwide
This study sought to derive thermal and hysteresis models of actuation systems employing thin film NiTi. Future actuators are likely to exploit the high energy densities available from NiTi; however, an impediment to its application in high-bandwidth actuators has been the slow thermal time constants associated with the bulk material. High-bandwidth actuators using thin film NiTi show great promise due to the increased rates of heat transfer. This grant supported the design, fabrication, and characterization of a NiTi bubble actuator and the fabrication, testing, and excitation of a silicon beam's first resonant mode with a NiTi thin film. This grant also supported the development of the authors' thin film processing techniques. (6 figures)
