Sway Reduction of Tower Crane

Tower crane is a common fixture at any major construction site. They often rise hundreds of feet into the air, and can reach out just as far. Tower crane has a problem that a fast transfer of the load causes sway of the load. It takes a long time sometime to lift up and unload the load due to the wind and other disturbances. The objective of this project is to minimize the sway of the load suspended on the tower crane by developing a control method by using a concept of spherical pendulum and delayed position feedback. Develop equation for controller and solve using numerical simulation. From the result gained, the best method can be used to minimize the sway of the tower crane.
