As a kind of vehicle, mechanical structure and the site operation of bridge cranes are relatively simple, it is widely used in industrial applications, such as production workshop and cargo handling field. This paper takes the bridge crane in copper electrolysis workshop as an example, high control performance of their job requirements is analyzed, and active anti-sway motion control system of bridge crane is designed. This paper proposes a bridge crane positioning sliding surface structure control as anti-sway control method, combined with the model and the nonlinear sliding mode control characteristics, a pure mathematical calculation is designed controller for multi-input and multi-output controller. It is difficult to determine the design parameters of sliding mode, then put forward the parameters optimization of sliding mode using genetic algorithm, and verified the validity of the proposed method, at the same time, it is possible to apply sliding mode control anti-sway method for industrial crane. The MATLAB results show that the scheme has good control effect, and is an ideal control method.
