Paper Abstract

Aimed at the traditional weight measurement system's shortcomings of bad stability, low precision and complicated circuit, a high precision based on chaotic circuit is put forward. One of its outstanding characteristics is to make use of the high sensitivity to initial values of chaotic system and apply chaotic theory to weight measurement. Besides, through adopting a voltage controlled by constant-current sourced to produce charge current or discharge current, linearity and stability of the measurement system is increased. In addition, the system has great adaptability and simple circuit. The theoretic error range of this system is less than ±0.1μg, and the theoretic resolution is 0.01μg, which are verified approximately by experimental statistics.
