Abstract:
An attitude-control algorithm for ejection seats on “H” shaped motor is presented in this paper. The control algorithm is based on time-sharing strategy, and the parameters in algorithm are optimized by using PSO method. Through simulating under Matlab/Simulink in different ejection conditions, the infection of time-sharing strategy in attitude-control is analyzed, and the minimum safe altitude is compared with K36D-3.5A, ACES II and 120 ejection conditions in GJB 1800A-2007. The simulation results and analysis show that this control algorithm on “H” shaped motor can improve escape performance at low-altitude and adverse-attitude, thus proving the algorithm in this paper to be reliable and effective.
