By simulation and test , provided with weighing system and fuzzy - pid control arithmetic , the diameter control system achieve marked advance in dynamic performance , stable precision and diameter precision . it will have proud application foreground if the system is popularize to crystal growth industry 通过仿真分析以及实验测试，采用模糊pid控制算法以及上称重数据采集系统的等径控制系统，在动态性能、稳态精度、控径精度上都有较大程度的提高。该系统推广到晶体生长工业中，将有着重大的应用前景。
The input value of static weighing system is instant and the interference is small . nsr is high , then interference signal is ease to dispose . while dynamic weighing systems have different signal modes , yawp interference magnitude size and mode when it is in different facilities and different testing objects . in this thesis has optimum attempt in this point and find a solution which has perfect practicality 动态定量称量技术是一项很有前景的技术，在我国发展也有很久了，但是这方面的技术还是不成熟，由于动态比静态称量要复杂得多，静态称量由于输入值是恒定、干扰小、信噪比大，干扰信号易处理；而动态称量系统对不同的设备、不同的测试对象产生的信号形式、噪声干扰大小、方式均不同。
Dynamic weighing system is as a second - order system and set it up model , then has its transform function laplace transform and z transform , at last has a formula that m is only relation to the system parameters . this article has system identified with the recursive least square ( rls ) method , and has the system parameters , while the auto - regressive - moving - average ( arma ) model for the second order weighing system is firstly derived . and has a equation which the mass is only correlation to the system parameters 论文具体分析了定量称量问题，首先是把称量系统看作是一个二阶系统，建立数学模后，进行拉普拉斯变换和z变换后得出一个质量仅与系统参数有关的关系式，从而把称量问题转化为一个系统参数识别问题来解决。通过编写的程序来采集系统信号并进行处理(运用渐消递推最小二乘法)对系统参数进行识别，从而得出称量结果。
