摘要: 对摆式列车倾摆控制系统的实际线路采集信号进行分析,采用切贝雪夫逼近设计有限冲激(FIR)低通 数字滤波器,分析了信号经过滤波后产生滞后的原因,提出了滞后的补偿办法。给出了超高阈值的选取,介绍了 DSP技术,采用TMS320C40实现数字滤波器,得到可以实际应用的数字滤波器。Abstract: The signal of the control systemof tilting trains is analyzed and compensated for time delay. FIR lowpass digital filter, which can be used to obtain control signal, is designed on the basis of Chebyshev approach. The reason why the time delay of signal is caused is given. The digital signal processor is introduced and the digital filter is achieved byTMS320C40.
