【摘要】 回旋加速器、静电加速器及同位素电磁分离器等物理装置,其磁场是由磁场电流稳定系统供电及稳定的。本文叙述电磁分离器的稳流系统的瞬变过程、动态品质的两个指标(σ_max、t_p)。指出在稳态电流准确度较高(2×10^-4)时系统是一个稳定的但又是一个欠阻尼的系统。在串入一个比例—积分校正环节（PI环节）后,系统的动态品质得到很大的改善,同时也提高了稳态电流准确度。更多还原

【Abstract】 The magnetic fields in the electromagnets of nuclear physics sets suchas cyclotron, static generator and electromagnetic isotope separator aresupplied and stabilized by the stabilized current system. In this paper thetransient of the electromagnet current and two indicators(σ_max, t_p) of dyn-amic quality of current in electromagnetic isotope separator are studied.The data suggested that if the accurcy of electromagnet stabilized currentis high, the stabilizator is of underdamp, but the system is still stable.When proportional, integral corrector (PI)is used in sesies with DC Volta-ge amplifier, the dynamic quality of the system is greatly improued, at thesame time the current stability of the stabilizer is also greatly increa sed.更多还原
