Overhead Crane experimental model using Simmechanic Visualization is presented for the robust antisway
LQR control. First, 1D translational motion of overhead crane is designed with exact lab model
measurements and features. Second, linear least square system identification with 7 past inputs/outputs is
applied on collected simulation data to produce more predicted models. Third, minimize root mean square
error and identified the best fit model with lowest RMSE. Finally, Linear Quadratic Regulator (LQR) and
Reference tracking with pre-compensator have been implemented to minimize load swing and perform fast
track on trolley positioning.
