Flatness Based Control of an Industrial Robot Joint Using Secondary Encoders

Flatness-based control of an irrigation canal using SCADA

With a population of more than six billion people, food production from agriculture must be raised to meet increasing demand. While irrigated agriculture provides 40% of the total food production, it represents 80% of the freshwater consumption worldwide. In summer and drought conditions, efficient management of scarce water resources becomes crucial. The majority of irrigation canals are manag...

Differential flatness applications to industrial machine control

In this article the applications of differential flatness to some industrial systems are presented. Computational methods of obtaining the flat output and the straight forward method of constructing the corresponding control law are given. Some theoretical and industrial systems are used as illustration including the third order synchronous machine model and the one degree of freedom magnetic l...

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...

3D Vision-Based Control On An Industrial Robot

This paper investigates the relative target-object (rigid body) pose estimation for vision-based control. A closedform target pose estimation algorithm is developed and implemented. Moreover, PI-based visual control was designed and implemented in the camera (sensor) frame to minimize the effect of errors in the extrinsic parameters of the camera. The performance of the vision-based control alg...
