Trajectory Control of Crane Load Position and Inclination
نویسندگان
چکیده
A gain-scheduled trajectory control is exemplary presented for two of six available axes of an overhead crane that allows for positioning and inclining the crane load according to specified trajectories. Besides its tracking capabilities, the proposed control provides an active oscillation damping. The overall control structure consists of independent axis controllers, which are adapted to measurements of varying system parameters. These axis controllers take advantage of combined feedforward and feedback control as well as observer based disturbance rejection. The achieved control performance is shown by selected experimental results from an implementation on a 5 t bridge crane. Copyright @ 2002 IFAC

Flatness Based Control of a 3-DOF Overhead Crane With Velocity Controlled Drives
As an example of a spatial manipulator with large work space a 3-DOF overhead crane is considered. A nonlinear model of the overhead crane, including drive dynamics, is derived. The drives of trolley and winch are controlled by velocity controllers. Therefore the dynamics of the drives can be approximated and thus included into the model description. The states of the system are parameterized b...
متن کاملThe Effect of Base Position on Maximum Allowable Load of Dual Arm Robots
A new computational technique is presented to find the optimal base position of dual arm robots in order to carry maximum allowable load. The maximum allowable load on a desired trajectory is limited by the number of factors such as; actuators torque limits, kinematic constraints, and kinematic redundancy of cooperative manipulators. For a dual arm robot mounted on a rail or table, load works...
متن کاملPosition and inclination control of a passive disk based on cyclic motion generation
We propose a position and inclination controlling method for a passive object using an active plate. Previously, we proposed a novel manipulation scheme that can control a passive object’s orientation using an active plate. In the work, stable plate cyclic motion is designed and inclination control of the object is realized. However, the object’s position is not considered, so there is a possib...
متن کاملApplication 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 کاملAnti-swing Fuzzy Controller Design for a 3D Overhead Crane
This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...
