Anew twice-comparison instantaneous floating-point amplifier with sign bit is recommended in this paper. This amplifier only consists of four amplification stages, the first stage being for 48dB amplification, and the second, third and fourth for 12dB respectively. This amplifier first determines whether the output potential of the first amplification stage is above 8V, then simultaneously judges if the potential of each input of the second, third and fourth stage is above 2V. The judgments decide which stage...

Anew twice-comparison instantaneous floating-point amplifier with sign bit is recommended in this paper. This amplifier only consists of four amplification stages, the first stage being for 48dB amplification, and the second, third and fourth for 12dB respectively. This amplifier first determines whether the output potential of the first amplification stage is above 8V, then simultaneously judges if the potential of each input of the second, third and fourth stage is above 2V. The judgments decide which stage should be switched on or off. Only two times of judgment (comparison) are needed altogether. Its time for amplifying one signal sample is only half the time of three time-gain-regulation amplifier.

本文提出了一种新型的带有符号位的二次比较型瞬时浮点放大器,它是将通常用的七阶放大改为四阶放大。第一阶为48dB放大级,第二、三、四阶为12dB放大级。其基本原理是:第二、三、四阶入口处电位是否达到2V的判别要同时进行,判别之后开关状态才发生改变;加上第一阶48dB放大级输出是否大于8V的判别,共进行了两次比较。从而使放大一个子样的时间仅为三次增益调整型时间的一半。

Power regulation system of China Experiment Fast Reactor (CEFR) consists of ionization chamber, regulation amplifier, dead zone and limiter, power amplifier and stepping motor, reducer, and regulation rod. In this paper, the mathematical models of the parts of the system are introduced, and the dynamic analysis of system is carried out. The analysis results show that the application of proportional rule to system is feasible. When KN is less than 5000, the system is stable. When step reactivity disturbance is input to the system, the maximum overshoot of the system increases with the disturbance amplitude, and is independent of KN. Time delay is disadvantageous to the system, but just has a little effect on it. KN can be within the range of 300 to 600. When KN is 300, and is 8×10-5/s, the maximum overshoot of system is less than 3%PD, and setting time less than 7s. When is 4×10-4 step disturbance, the maximum overshoot of system is less than 8%PD, and setting time is less than 5s. If KN is less than 5000, and without limiter, the dynamic characteristic of system is better.

中国实验快堆(CEFR)功率调节系统由电离室、比较器、调节放大器、死区与限幅装置、功放驱动及电机、减速器、调节棒组成。本文介绍了该系统中各环节的数学模型,对系统进行了动态分析。分析结果表明,本系统采用比例调节是可行的。KN小于5000时,系统不会出现不稳定的现象;在阶跃反应性扰动 情况下,系统的超调量随输入扰动幅度的增大而增大,与KN的大小无关;延迟环节对系统不利,但影响不大; KN可以在300~600之间取值,当KN取300,n~=8×10-5s-1时,超调量小于3%PD,调节时间小于7s;n~=40×10-5s-1阶跃时,超调量小于8%PD,调节时间小于5s;当KN小于5000且无限幅环节时,系统动态特性更好。
