Identification of a Nonlinear Function in a Dynamical System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using an adaptive method introduced in (Messner et al., 1991), a standard identification technique for linear systems can be extended to identify nonlinear functions in dynamical systems under ...
Time Optimal Seek Trajectories for a Dual Stage Optical Disk Drive Actuator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A closed-form solution for the time optimal control of a dual actuator disk drive system that takes into account the physical constraint limiting the relative motion of the fine and coarse ...
Stability and Resolution Analysis of a Phase-Locked Loop Natural Frequency Tracking System for MEMS Fatigue Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analysis of a nonlinear control system that was used to track the natural frequency of a MEMS resonator is presented in this paper. A phase-locked loop system is used to track the natural ...
Tracking Control of Robot Manipulators Using a Robust Deterministic Control Law
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There have been theoretical developments on the control of dynamic systems based on deterministically uncertain and singularly perturbed models in recent years. In this paper, a robust deterministic ...
Functional Persistence of Excitation and Observability for Learning Control Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Adaptive systems involving function learning can be formulated in terms of integral equations of the first kind, possibly with separable, finite-dimensional kernels. The learning process involves ...
Experimental Implementation of a Deterministic Controller for a D.C. Motor With Uncertain Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The control of d.c. motors is often complicated by the fact that the dynamics of the system to be controlled are unknown. In this paper a deterministic controller is employed to control a ...
Implementation of Adaptive Techniques for Motion Control of Robotic Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with the digital implementation and experimental evaluation of two adaptive controllers for robotic manipulators. The first is a continuous time model reference adaptive ...
