摘要
研究了数模转换器(DAC)分辨率对ATP系统跟踪精度的影响。给出了精跟踪系统结构、控制算法及设计参数,建立了精跟踪系统Matlab/Simulink仿真模型,通过仿真得到了DAC不同分辨率对跟踪精度的影响。结果表明,当DAC分辨率提高到16bit时,跟踪精度接近最佳,继续增加分辨率对提高跟踪精度贡献不大。
The paper researchs the effect of DAC resolution on the tracking accuracy of ATP system. The structure, control algorithm and design parameter of fine tracking system are given, the fine tracking system simulation model is built based on Matlab/Simulink, by means of simulation, the effect of DAC resolution on tracking accuracy is obtained. The results show that, when the resolution is 16bit, the accuracy is close to the highest, there is little contribution to improve tracking accuracy when continue to increase the resolution.
