摘要
为了提升特种起重机伸缩臂控制精度,提出基于模糊PID融合的特种起重机伸缩臂自动控制方法。针对特种起重机伸缩臂的整体结构,对伸缩臂受力展开了分析。以受力分析结果为基础建立伸缩臂数学模型,对该模型进行推导后获取伸缩臂传递函数,将其与设计的模糊PID融合控制器相结合,实现对特种起重机伸缩臂自动控制。实行位移响应测试、末端姿态位置与末端作用力测试,测试结果表明,所提方法所得结果与期望值基本一致,说明该方法的精度高、可靠性强。
In order to improve the control accuracy of telescopic boom of special crane,an automatic control method of telescopic boom of special crane based on fuzzy PID fusion is proposed.According to the overall structure of the telescopic boom of special crane,the stress of the telescopic boom is analyzed.Based on the force analysis results,the mathematical model of the telescopic boom is established.After deriving the model,the transfer function of the telescopic boom is obtained,which is combined with the designed fuzzy PID fusion controller to realize the automatic control of the telescopic boom of special crane.The test results show that the results obtained by this method are basically consistent with the expected value,which shows that this method has high precision and strong reliability.
