CONTROL 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 کاملImpedance Control of Flexible Robot Manipulators
Force control is very important for many practical manipulation tasks of robot manipulators, such as, assembly, grinding, deburring that associate with interaction between the end-effector of the robot and the environment. Force control of the robot manipulator can be break down into two categories: Position/Force Hybrid Control and Impedance Control. The former is focused on regulation of both...
متن کاملAn Adaptive Impedance Controller for Robot Manipulators
A desired dynamic behavior of constrained manipulators can be achieved by means of impedance control and various implementations of fixed controllers have been proposed. In this paper, and adaptive implementation is presented as an alternative to reduce the design sensitivity due to manipulator mismatch. The adaptive controller globally achieves the impedance objective for the nonlinear dynamic...
متن کاملA New Type-2 Fuzzy Systems for Flexible-Joint Robot Arm Control
In this paper an adaptive neuro fuzzy inference system based on interval Gaussian type-2 fuzzy sets in the antecedent part and Gaussian type-1 fuzzy sets as coefficients of linear combination of input variables in the consequent part is presented. The capability of the proposed method (we named ANFIS2) to function approximation and dynamical system identification is shown. The ANFIS2 structure ...
متن کاملA New Model for Flexible-joint Robot Manipulators
We propose a new model for robot manipulators with rigid links and flexible joints. Our model is expressed in Cartesian dependent coordinates which represent the positions, orientations and velocities of the links and the rotors, as opposed to independent generalized coordinates in which classical “Lagrangian” models are defined. The model consists of a set of dynamics equations and holonomic c...
