摘要
测力轮对标定试验台在进行轮对标定试验时,需要先将轮对移动至钢轨面上,然后在对其进行加载,其中移动和加载的同步性都将影响标定结果的精度。在分析多种同步控制技术优缺点的基础上,结合轮对标定试验台加载的特点,将其分为位置同步和力同步两个环节,分别应用主从式和交叉耦合式同步控制。同时对不完全微分PID控制算法进行了改进,作为各个控制器算法。该方式很好的分离了位置同步和力同步两个过程,根据过程特点充分利用了相应同步控制方式。试验结果表明,该控制方式和新型改进PID的综合应用,很好的提高了系统的同步性能和控制精度,加快了响应速度,同时也避免了复杂的控制算法。
When wheel load calibration test on wheel for calibration experiment was carried out,firstly needs to move the wheel to the rail surface,and then to loading,in which mobile and load of synchronicity will influence the accuracy of the calibration results. Synchronization control technology based on the analysis of a variety of advantages and disadvantages,on the basis the characteristics of wheel load calibration test bed, it can be divided into position synchronization and synchronization of two links,which are master-slave type and cross coupling type synchronous control respectively. And the incomplete differential PID control algorithm is improved,as the controller algorithm. The way is a good separation of the position synchronization and synchronization of two processes,according to process characteristics it makes full use of the corresponding synchronous control mode. The test results show that the integrated application of control method and the new improved PID,is good to improve the synchronization performance and control precision of the system,accelerating the response speed,also avoiding the complex control algorithm.
