    Stability analysis of the electronic balance by root-locus technique

      摘要
    • 摘要: 本文将TG588B型阻尼分析天平改装成发光=极管(LED)数字显示的电子天平,用根轨迹法从理论上探讨提高该天平稳定性的途径和方法,並在实验中得到了证实。该天平的最大称量比扭力式电子天平约大两个数量级,为199.9克。其灵敏度、线性度和稳定时间分别为0.001克、0.05%和0.5秒。

       

      Abstract: In this study a TG 528B damping analysis balance is reformed into an electronic balance with LED digital display. The stability analysis of the electronic balance is conducted by root-locus technique and put into pactice with satisfaction. The maximum capacity, sensitivity, liuearity and stable time of the electronic balance reaches up to 199.9g, 0.001g, 0.05% and 0.5 second, respectively.
