摘要:
研究了一种基于“H”形火箭包的弹射座椅控制通道解耦算法。介绍了三通道非同时可控约束条件下,基于矛盾方程组求解技术的弹射座椅控制通道解耦算法的设计与实现。在Matlab/Simulink平台上基于4种不同需求的约束条件进行了仿真验证,分析了解耦算法中约束条件及阈值的设定对座椅控制通道解耦效果的影响。仿真结果表明,基于“H”形火箭包的弹射座椅控制通道解耦算法在满足所有约束条件的同时,能够将各控制通道耦合力矩限制到主力矩的10%以下,因此证明了新算法具有较高的可信性和实用性。

Abstract:
A control channel decoupling algorithm for "H" structure of ejection seats is presented in this paper. Under the constraint condition of three channels non-simultaneous controllable, the decoupling algorithm is designed based on contradiction equations solution. The simulation is achieved under Matlab/Simulink in accordance with 4 different constraint conditions. The influence of the constraint condition and the threshold value in contradiction equations are analyzed. The simulation results and their analysis show that, under all the constraint conditions, the decoupling algorithm for "H" structure of ejection seats can reduce each coupling moment to 10 percents of the corresponding main moment, thus proving the algorithm in this paper to be reliable and effective.
