数字式气体质量流量计动态补偿器的设计与实现

Design and realization of dynamic compensation of gas mass flowmeterbased on fuzzy control theories

为快速、精确测量气体质量流量,通过分析流量计中气体流量的变化规律,提出一种基于模糊控制方式的数字补偿算法。并将此算法应用于以ARM处理器为核心的数字式气体质量流量计中。实验证明,该方法能够明显改善热式传感器的动态响应速度,实现其快速补偿。

Proposed in this paper is a digital compensation algorithm developed on the basis of fuzzy control theoties. Experiments on the gas flow patterns in the flowmeter prove that the algorithm used in ARM Digital Gas Mass Flowmeter is capable of significantly improving the sensitivity of the heat sensor, hence superior in terms of the measurement of gas mass flow.
