Pendulum control method based on anti- sliding eot crane system

As an important bridge crane lifting and transport machinery , in industrial production has been widely used. Controls for overhead cranes are often required for control accuracy , speed and other aspects of a comprehensive anti- pendulum consideration . Trolley horizontally moving the motor by direct control , and therefore the speed and movement of the trolley is easier to achieve precision control . contrast, anti- swing bridge crane system, the crane is often difficult to achieve . mainly due to the swing of the load acceleration, deceleration, and outside interference caused by anti- swing control for crane operation safety is often crucial. currently , research on the overhead crane system has many times the minimum time control of overhead crane systems , using overhead gantry crane method gives an object-based model anti- swing control strategy ; adopt minimum time control thought , would bang-bang control of a group of switching time is defined as the value of a new variable , and through a set of fuzzy control to find the optimal switching time sequence ; study is crane model of a linear time-varying, also uses the optimal control strategy and the characteristics of varying parameters for the object presents a variable feedback gain state feedback control law . currently , intelligent control systems in the crane also has some applications.
