摘要
建立运载火箭双谐振点发动机的双质量弹簧物理模型,辨识特性参数,推导出伺服机构数学模型。采用直接数值寻优方法对推力矢量控制伺服机构算法进行计算优化研究,通过仿真分析和发动机冷摆试车试验,得出双陷波补偿是一种较优选择。
A double-spring-mass physical model is proposed for double-resonance-frequency engines in launch vehicles. The characteristic parameters are identified and the corresponding mathematical model for servo-mechanisms is derived. The optimization of servo-mechanism＇s control algorithm is studied using a direct numerical optimization method. Then, simulation analysis and trial experiments are completed. The result shows that double-notch filter is a more acceptable compensation method.
