Inverse dynamic analysis with feedback control for vibration-free positioning of a gantry crane system

Abstract

The inverse dynamic analysis is a simple method that is used for reducing the vibration and the sway angle for the gantry crane system. The shaped input function is derived from the specified output function. Third order exponential function is used as the desired output due to its asymptotic behavior. The simulation has been done to the gantry crane system which is fourth order system by using feedback control. In the proposed method the parameters that need to be defined is the position ofthe trolley and the sway angle of the mass. Simulated responses of the position of trolley and sway angle ofthe mass are presented using MATLAB. From the simulation results, satisfactory vibration reduction of a gantry crane system has been achieved using the proposed method.

Position Control of a 2D Nonlinear Gantry Crane System Using Model Predictive Controller

“…Gantry crane are increasingly being used in harbours and factories for various industrial applications to grip, lift and transport heavy payload to the desired location as fast and accurate as possible. Gantry crane system (GCS) is usually supported by two or more legs [1]. The trolley is designed on the top of GCS to transport heavy objects either in left or right direction along the horizontal bridge rail of a crane until located to the desired position [2].…”

Flatness Based Control of a 3-DOF Overhead Crane with Velocity Controlled Drives

“…Auernig and Troger (1987). Since then a lot of different controllers and control methods for overhead and boom cranes have been developed, either linear controllers Yanai et al (2001); Piazzi and Visioli (2002); Ahmad et al (2009) or nonlinear strategies Fliess et al (1991);O'Connor (2002); Yusop et al (2008); Lee (1998); Kiss et al (2001); Almutairi and Zribi (2009). Anti sway control of overhead cranes is applied to reallife system e.g.…”
