As an active method for avoiding swing, electronic anti-swing is not dependent on the driver’s experience and can combine swing-decreasing with movement-control to improve the efficiency of crane, and lighten the intensity of drivers. Therefore, it will be used widely for loading of port and factory. In this thesis, the mathematical model of the overhead crane motion system is established and the simulation model is also built with MATLAB/Simulink. The two closed-loop PID controller is designed to achieve the control of anti-swing and orientation. Comparing with the controlling results of using conventional PID algorithm as a controller on different disturbance conditions, we can find that it is difficult to meet the accuracy requirements of the practical operation of crane system which has easily variable control parameters in the process of running. So we design the nonlinear PID whose variable parameters change with error. The results of simulation indicate that the steady-state error can be eliminated, and the response time of system can be shortened, in addition, the disturbance rejection ability of system can be strengthened. Then, we complish the digital realization of PID control strategy with increment PID control algorithm. At last, the state feedback controller is designed based on linearized model of crane system and the controller gain can be obtained by the LQR method. The results of simulation show that the control strategy is also satisfactory.
