The main goal of this work is to reduce the liquid/gaseous nitrogen ($L{N}_2$ / $G{N}_2$) waste on thermal-vacuum space tests. In this paper, we present the results of a feasibility investigation of the optimal control techniques in this issue. It is found that it is possible to reduce the overall consumption by approximately 5% during thermal balance/thermal cycling space test campaigns. Therefore, optimal control techniques improve the best practices on those activities.

通过最佳控制降低空间测试的成本

这项工作的主要目的是减少液/气态氮（$\mathrm{大号}{ñ}_{\mathrm{2个}}$ / $G{ñ}_{\mathrm{2个}}$）浪费在热真空空间测试上。在本文中，我们介绍了本期最佳控制技术的可行性调查结果。发现在热平衡/热循环空间测试活动期间可以将总消耗降低约5％。因此，最佳控制技术可以改善这些活动的最佳实践。
