摘　　要：在空间动力装置研制中,需模拟空间的真空状态进行点火试验。真空舱的压力应与所对应空间的压力相同并保持稳定。针对某空间模拟试验系统配套的舱压调节系统设计,结合舱压稳定保持的需求,在分析影响舱压稳定的主要因素基础上,以真空舱内的压力信号为目标函数,确定了采用主、被动控制的补气和PID算法的控制策略;开展了仿真模拟计算和分析,实现了系统和结构的优化,满足了动力装置热试车试验的使用要求。In the research of space propulsion system,need simulate the ignition test in the space vacuum state.The vacuum chamber pressure should be the same as it in the corresponding space and be stable.We design a cabin pressure regulation system for the space simulation experiment system.Consider the main influencing factors and keep steady of the cabin pressure,take the vacuum chamber pressure signal as the objective function,Make sure the primary and passive air supplement and PID algorithm.By simulating and analyzing the result,the system can meet the space propulsion s experiment require.
