A mathematical model of liquidnitrogensystem of a space environmental simulator is introduced and a quasi-stationary control method is developed in this paper.
It has been proved by test that the problem of large space simulator liquidnitrogensystem starting has been solved successfully in simulator liquidnitrogensystem.
通过初步调试证明,液氮系统能够很好地解决大型空间环境模拟设备液氮系统启动困难的问题。
