VIBRATION CONTROL OF A GANTRY CRANE SYSTEM USING INVERSE DYNAMIC ANALYSIS

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 a 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 the trolley and sway angle of the mass are presented using MATLAB. The performance of the Bang-bang input technique and the inverse dynamic analysis are compared. From the simulation results, satisfactory vibration reduction of a crane system has been achieved using the proposed method
