摘　　要：提出并实现了一种科氏质量流量计的新型数字闭环系统。其闭环幅度控制基于数字信号处理方法和数字控制律,改善了系统的动态品质、稳态精度和抗干扰能力;系统设计综合了模拟技术和数字技术优势,降低了硬件成本和算法复杂度。A novel digital closed loop system of Coriolis mass flowmeter （CMF） is devised and realized. Closed loop amplitude control is based on digital signal process methods and digital control rules, so as to improve dynamic response, static precision, and environment adaptability. According to practical requirements, a hardware scheme that combines advantages of both analog and digital technology is employed, so that the hardware cost and algorithm complexity can be reduced, and the total performance can be improved.
