电力机车粘着控制中滤波环节的优化设计方法

Computer-Aided Design Method of Adhesion Control of Locomotive

研究电力机车粘着控制中滤波环节设计优化的问题。在电力机车的粘着控制研究中,传统滤波环节操作繁琐,依靠运行实验反复调试,对控制程序改动大导致实验成本较高,没有形成有效的设计方法。为克服上述问题,采用MATLAB工具与FPGA平台相结合的计算机辅助设计方法,解决了实验中滤波环节的设计问题。利用FDATools设计所需要的滤波器并结合Fdesign实现数据定点化,之后利用Simulink-Modelsim联合仿真并转换Verilog HDL代码,在FPGA平台上得以实现。仿真结果表明,上述方法在保证了良好滤波效果的基础上,大幅缩短设计时间,使得在车辆实验中便于快速修改,同时也为后续的粘着控制板卡制作提供了理论参考。

This research focused on the problem of filter - optimization design of locomotive adhesion control. In the adhesion control research, traditional filter design method is cumbersome, the big change of the control program leads to a higher cost of experiments. According to this problem, a computer - aided design methods based on FPGA was proposed to filter many kinds of noises effectively, which can help to identify the slipping point and measurement singular point. This method designs filter by FI）ATool, point - fixed by Fdesign, and transformed the Simulink - Modelsim model into Verilog HDL code, which can run on FPGA platform. The simulation results show that this method not only can filter many kinds of noises and shorten the design time, but also provides a theoretical basis for subsequent study of adhesion control board production.
