Abstract:

To realize the synchronous control on the dual-motor in the hoisting system of a large crawler crane, a fuzzy PID control strategy was proposed. The fuzzy reasoning was applied to self-tuning of the PID parameters to compensate the synchronous error carrsed by the nonlinearity and time-variation of the synchronous system. The results of simulation and experiment showed that, compared with the conventional PID control, the fuzzy PID control is characterized by less overshoot,more rapid tracking, and better robustness, it is better for the synchronous system of the dual-motor in the crane.

Key words: hydraulic transmission and control, crane, synchronization control, fuzzy-PID control, simulation
