Design of an optimum anti-G suit controller using an adaptive feedforward control scheme

An effort was made to design an anti-G suit valve controller based on ideal pressure profiles. A computer simulation of the cardiovascular model developed at Wright State University was used to obtain the optimal pressure profiles. The model developed by Jaron and Chu (1984) was used for this simulation. The simulation results show that an optimal duration for the pressure profiles that provides the maximum Gz tolerance exists. The results clearly contradict the belief that the faster the suit filling, the better the design and higher the G-tolerance. An anti-G suit valve controller using an adaptive feedforward control scheme was designed to produce the ideal pressure profiles
