| Abstract: | The modeling and simulation methods of space suit portable life support system (PLSS) based on Simulink were discussed. A lumped parameter approach was used to model the life support system. The model could calculate various parameters include temperature, humidity, and CO2 concentration. Dynamic model of the current USA extravehicular activity (EVA) space suit PLSS was developed for simulation studies. Analysis results show that the test bed can evaluate the dynamic performance of EVA space suit PLSS reasonably. The model is provided with modularity and flexibility, and the method are of significance for the research and optimization of space suit PLSS in our country. |
