The dynamic model of overhead crane was derived with Euler-Lagrangian method. The characteristic of passivity of system was analyzed,and a control Lyapunov function was structured. A stabilization derivative control-ler combined with fractional order was designed,and the best application interval of fractional order gama was stud-ied. The simulation results showed that the controller realized accurate positioning of trolley and obvious anti-swing of load,which verified the effectiveness of the proposed control scheme.
