Two-Time Scale Force and Position Control of Flexible Manipulators
The problem of controlling force and position of a exible link manipulator in contact with a compliant environment is considered in this paper. Using singular perturbation theory, a slow subsystem associated with rigid motion dynamics and a fast subsystem associated with link exible dynamics are identi ed. Hence a two-time scale control strategy is adopted, consisting in a force and position co...
متن کاملCONTROL OF FLEXIBLE JOINT ROBOT MANIPULATORS BY COMPENSATING FLEXIBILITY
A flexible-joint robot manipulator is a complex system because it is nonlinear, multivariable, highly coupled along with joint flexibility and uncertainty. To overcome flexibility, several methods have been proposed based on flexible model. This paper presents a novel method for controlling flexible-joint robot manipulators. A novel control law is presented by compensating flexibility to form a...
متن کاملDynamics of Flexible Manipulators
This paper presents an application of Continuum (i.e. Lagrangian) and Finite Element Techniques to flexible manipulator arms for derivation of the corresponding Dynamic Equations of Motion. Specifically a one-link flexible arm is considered for detailed analysis, and the results are extended for the case of a two - link flexible manipulator. Numerical examples are given for the case of both one...
متن کاملRobust Hybrid Motion Force Control Algorithm for Robot Manipulators
In this paper we present a robust hybrid motion/force controller for rigid robot manipulators. The main contribution of this paper is that the proposed hybrid control system is able to accomplish motion objectives in free directions and force objectives in constrained directions under parametric uncertainty both in robot dynamics and stiffness constraint constant. Also, the given scheme is prov...
متن کاملTrajectory Control of Flexible Manipulators
We present some feedback control techniques recently developed for the exact solution of t rajectory tracking problems for manipulators with flexible elements. Two classes are considered: i) robots with rigid links but with elastic transmissions, in which flexibility is concentrated at the joints, and ii) robots with lightweight and/or long arms, where flexibility is distributed along the links...
