One purpose of lower body negative pressure (LBNP) chambers is to simulate the transition from microgravity to Earth-gravity. Physiological tests are conducted to assess stresses upon the cardiovascular system during these simulations. In general, the internal negative air-pressure of LBNP chambers is controlled with a proportional control system using only air-pressure as input. This can lead to an uncomfortable environment for the test subject. The proposed LBNP chamber uses a proportional integral derivative control program, which uses temperature, humidity and airflow in addition to the traditional air-pressure as inputs. These proposed additional parameters would serve to better control the internal environment of the LBNP chamber.
