The invention discloses a crane open loop optimal anti-rocking control method. Based on the crane kinetic analysis, crane operation state parameters are used as boundary constraint conditions to realize anti-rocking control of shortest crane operation distance, shortest acceleration or deceleration operation time and optimal operation trajectory; and a mathematical model among the crane operationspeed, the operation time and the lifting rope length is built synchronously based on the numerical value analysis and the computer simulation technology. The open loop optimal control method is builtbased on optimal operation distance and acceleration or deceleration time; and the control method has the characteristics of short anti-rocking distance, high response speed and the like, can effectively inhibit the load deflection, improves the crane operation safety and operation stability, is simple in implementation, easy to realize engineering application and high in control precision, and facilitates the crane intelligent and automatic transportation.
