为提高工业CT射线源-探测器双轴位置伺服同步运动的定位精度、跟踪精度与同步精度等性能,提出了一种基于智能融合的交叉耦合同步运动控制策略。分析了控制品质的影响因素,建立了运动控制的数学模型,研究了相关控制策略,针对不确定性难题提出了基于智能融合的同步运动策略。以双轴系统结构同步控制为例,基于Matlab/Simulink环境进行了仿真的对比实验研究。系统响应曲线表明:提出的控制策略具有较强的位置指令跟踪、同步与抗干扰性能。实验结果证实所提出的智能融合控制策略是合理、可行的,控制跟踪精度较高。

In order to enhance the accuracy in positioning, tracking and synchronization of servo synchronous motion for ray source-detector biaxial position, the paper proposed a sort of control strategy of cross-coupling synchronous motion based on intelligence fusion. In the paper, it analyzed the influence factors, researched on the related control strategy, and aimed at the uncertainty puzzle it proposed the strategy of synchronous motion based on intelligence fusion control, It took the synchronous control of biaxial system structure as an example, made the contrast experiment research of simulation based on Matlab/Simulink environment, and the curve of system response demonstrated that the proposed control strategy could take on stronger performance in tracking ＆ synchronization of the position command and anti-interference. The results of experiment research validate that the proposed control strategy of intelligence fusion is feasible and reasonable, and higher in control tracking precision.
