摘要
中小型水闸的施工过程中,混凝土浇灌等环节会诱发搅拌机器设备的振动。传统的PID振动控制方法需要大幅调整参数,容易引发参数过量失调,振动控制效果不佳。本文提出基于模糊自适应PID控制算法的中小型水闸施工设备冲击振动消除方法,计算V带基准长度,通过运算获取实际中心距离,详细描述了中小型水闸施工设备机带轮振动关系,计算热冲击振动信号与控制参数之间的关联性,并对热冲击振动信号进行离散化处理,对离散化处理结果进行误差补偿,实现热冲击振动消除。实验结果表明,利用改进算法进行中小型水闸施工设备冲击振动消除,能够有效提高消除的准确性,提高中小型水闸施工设备的应用价值。
In the concrete casting and other steps of small and medium-sized sluices’construction, the shock vibration of mixing machine equipment used to be induced. Using the traditional PID control method we need overhaul the parameters and it was easy to cause the excessive imbalance of parameters, so the vibration control effect was not good. Based on the fuzzy adaptive PID control algorithm, the shock vibration eliminating method of small and medium-sized sluice construc?tion equipment was proposed. First calculate the datum length of V belt, by calculations get the actual center distance, de?scribe in detail the vibration connection between the equipment machine’s belt and wheel in small and medium-sized sluice’s construction. Calculate the correlation between thermal shock vibration signal and the control parameters, con?duct the discretization against the thermal shock vibration signal and then proceed error compensation for the results, af? ter that the thermal shock vibration elimination will be realized. Experimental results show that using the improved algo?rithm to eliminate the shock vibration of small and medium-sized sluice’s construction equipment can effectively im?prove the accuracy of elimination, increase the application value of the small and medium-sized sluice’s construction equipment.
