Abstract

The inverse dynamic analysis is a simple method that is used for reducing the vibration and swing angle for the gantry crane system. The actual gantry . crane system will be interface with the MATLAB in Real-Time Workshop. The input of the crane is using inverse dynamic analysis. The shaped input function is derived from the specified output function so that the designer can choose the speed and shape of the motion within the limitations of the drive system. Third order exponential function is used as the desired output due to its asymptotic behavior. The experiment has been done to the actual gantry crane system which is fourth order system. In the proposed method the parameters that need to be defined is the position of the trolley and sway angle of the mass. Simulated responses of the position of trolley and sway of the mass are presented using MATLAB. From the simulation results, satisfactory vibration reduction of a crane system has been achieved using the proposed method.
