In order to solve the problem of mismatch exist between angular motions by Sustained-G Flight Simulator pilot through his proprioceptive receptors and visual receptors, the control algorithm of Sustained-G Flight Simulator is designed.The formulas relative to control input is derived;the mathematical model of human proprioceptive system is researched, the relationship between pilot's perceptual angular and rotating linear acceleration vectors and angular accelerations is given, based on that, the control algorithm of Sustained-G Flight Simulator is proposed, which can make a match existence between the angular motion perceived by Sustained-G Flight Simulator pilot and aircraft pilot. The simulation results show that the control algorithm presented can effectively solve the problem of mismathching existence between angular motions by Sustained-G Flight Simulator pilot through his proprioceptive receptors and visual receptors, and improve the flight realism of Sustained-G Flight Simulator.
