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

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 of the trolley and the sway angle of the mass. Simulated responses of the position of trolley and sway angle of the mass are presented using MATLAB. From the simulation results, satisfactory vibration reduction of a gantry crane system has been achieved using the proposed method.
