First, a model-based non-linear feedback control (feedback linearization) is evaluated and compared to a model-based feedforward control algorithm. This book is concerned with fundamentals of robotics, including kinematics, dynamics, motion planning, computer vision, and control.
Our goal is to provide a complete introduction to the most important concepts in these subjects as applied to industrial robot manipulators, mobile robots, and other mechanical systems. Abstract This report presents a new way to model and identify single-link flexible arms when Coulomb fnc- tion is present in the joint.
In order to isolate the effects of this nonlinearity, the ann model is divided into two submodels: motor and two are coupled through the torque at the base of the beam. A systematic methd is developed to obtain the dynamics of a lumped-mass flexible.

Control of a flexible beam such as that in flexible-link robot manipulators in many mechanical devices is very challenging, due in part to its intrinsic nature of unmodelled dynamics in a system.
Such a system is said to be subjected to nonholonomic constraints, hence its feedback control is difficult to realize. This paper presents the application of control design based on second-order pole Cited by: 1.
This paper studies the problems of tip position regulation and vibration suppression of flexible manipulators without using the model. Because of the two-timescale characteristics of flexible manipulators, applying the existing model-free control methods may lead to ill-conditioned numerical problems.

The dynamic model of a robot arm composed of flexible beams and revolute joints is developed using a Rayleigh-Ritz based substructure synthesis technique and the linear theory of elastodynamics. Low-degree power functions in space variables of each substructure (beam) are adopted as shape functions for the purpose of discretization.
