摘要 以PWM作为D/A的功能接口,分析了不同电路对转换精度的影响,提出了以PWM接口输出经滤波电路获得的精度与电路结构及参数之间关系的分析方法,初步确定了理论上分析转换精度的步骤与方法。并以TMS320F2812为例对其PWM通道实现D/A转换扩展功能的精度做了实例计算,验证了理论分析的可行性与准确性。为磁悬浮数字控制系统的设计与预知其设计精度之间的关联提供了理论基础,可以为相关设计提供借鉴与参考。 By analyzing the influence of conversion accuracy by different circuits using PWM as the D/A function interface,a novel method is successfully proposed to obtain the relationship between precision and circuit structure/parameters in PWM Channel output filter circuit.Besides,primary steps and methods of theoretical synthesizing converting accuracy are determined.The theoretical analysis is well agreed with experimental calculating results in TMS320F2812 case,where PWM Channel was used to realize D/A conversion.Therefore,such developed theory could be a basis for devising magnetic digital control system and predicting its relationship with the resulting accuracy,as well as providing a good experience for relative designs.
