Application of Independent Joint Control Strategy for Discrete-Time Servo Control of Overhead Cranes
In this study, a new servo control system is presented for the overhead crane based on discrete-time state feedback approach. It provides both robust tracking and load swing suppression. Inspired from independent joint and computed torque control in robot manipulator field, a new model is derived in which the crane actuators are considered as the main plant. The crane nonlinearities are then tr...
متن کاملPerformance Tests for Visual Servo Control Systems, with Application to Partitioned Approaches to Visual Servo Control
Visual servoing has been a viable method of robot manipulator control for more than a decade. Initial developments involved position-based visual servoing (PBVS), in which the control signal exists in Cartesian space. The younger method, image-based visual servoing (IBVS), has seen considerable development in recent years. PBVS and IBVS offer tradeoffs in performance, and neither can solve all ...
متن کاملAdaptive Speed Control of Three-Phase Induction Servo-drives Based on Feedback Linearization Theory
In this paper, based on feedback linearization control method and using a special PI (propotational integrator) regulator (IP) in combination with a feed-forward controller, a three-phase induction servo-drive is speed controlled. First, an observer is employed to estimate the rotor d and q axis flux components. Then, two input-output state variables are introduced to control the dynamics of to...
متن کاملModeling, Control and Simulation of Cascade Control Servo System for one Axis Gimbal Mechanism
The gimbal stabilization mechanism is used to provide the stability to an object mounted on the gimbal by isolating it from the base angular motion and vibration. The purpose of this paper is to present a model of control servo system for one axis gimbal mechanism using a cascade PID controller. The gimbal torque relationships are derived by taking into consideration the base angular motion. Th...
متن کاملVelocity Control of Electro Hydraulic Servo System by Tracking Method
This paper proposes an efficient Tracking method for velocity control of an electro-hydraulic servo system (EHSS) in the presence of flow nonlinearities and internal friction. The tracking method controller is a kind of feedback error learning structure. In the proposed method, the Feedback Error Learning (FEL) algorithm is used to control the velocity. There is no need to compute the system ja...
