摘要
控制精度问题实际上最终归结为数字的精度问题,滤波器的各系数以及每次运算的结果都是存储在有限长的存储单元中,因此,必然造成一定的误差。针对A/D变换的量化效应加以分析,估算其对系统控制精度的影响程度。
The accuracy and precision control system in fact can be ultimately boiled down to the accuracy of figures. However, with either a dedicated hardware or a digital filter software implementation of digital filters, of the filter coefficients for each operation and the results of the process are stored in the memory finite element, and therefore, necessarily lead to an error. This paper focuses on the analysis of quantitative A/D transform effect, and it also estimates its system precision control to the extent of the impact.
