港口桥式起重机吊重系统姿态的稳定性控制

Stability Control of Lifting Weight System of Bridge Crane

通过建立港口桥式起重机吊重系统的数学简化模型,提出基于位移和角度控制的模糊自适应PID智能控制方法,并在此基础上设计姿态稳定PLC控制系统,通过实验平台验证,该控制方法能够使得吊重系统迅速趋于稳定、响应速度较快,从而提高了起重机的工作效率和安全性。

By establishing a simplified mathematical model for the lifting weight system of bridge crane, this paper puts forward the intelligent control methods of fuzzy self-adaptive PID based on the proposed displacement and angle control, and designs the attitude PLC control system. The experiment shows that this control method can make the lifting weight system to keep stable quickly, resulting in improving the work efficiency and the safety of the crane.
