研究了一种基于＂H＂形火箭包的弹射座椅姿态控制算法。介绍了分时控制策略下，座椅姿态模糊控制算法的设计与实现。在 Matlab／ Simulink 平台上根据不同弹射状态进行了仿真，分析了控制算法对座椅弹射高度的影响，比较了该座椅与俄罗斯 K36D?3．5A 座椅和美国 ACES II 座椅在最低安全高度上的差异，并按国军标1800A?2007规定的120种弹射状态进行了该座椅性能与国军标规定值的对比研究。仿真结果表明，基于“H”形火箭包的弹射座椅姿态控制算法能够有效改善低速不利姿态下弹射座椅的救生性能，证明了新算法具有较高的可信性和实用性。

An attitude?control algorithm for “H” structure of ejection seats is presented in this paper. Fuzzy control algorithm is designed based on time?sharing strategy, and simulation is achieved under Matlab / Simulink in accord?ance with different ejection conditions. The influence of safe altitude caused by algorithm is analyzed, and the mini?mum safe altitude is compared with K36D?3.5A, ACES II and 120 ejection conditions in GJB 1800A?2007. The simulation results and their analysis show preliminarily that the fuzzy control algorithm for " H" structure of ejection seats can improve escape performance at low speed and adverse attitude, thus proving the algorithm in this paper to be reliable and effective.
