| 摘 要： | 火箭发动机燃烧室中燃烧过程的动力学模型是一不稳定时滞系统,用传统的线性状态反馈方法来镇定它,所得到的闭环系统对燃烧时滞及压力指数的鲁棒性很差.本文采用文[1]中提出的变结构控制方法来镇定该燃烧过程,所形成的闭环系统显著地改善了系统对燃烧时滞及压力指数的鲁棒性.

| Abstract: | The dynamical model of combustion in liquid propellant rocket motors is anunstable time-delay system. When it is stabilized by a linear state feedback controller, the robustness of the closed loop system is not satisfactory. In this paper, thevariable structure control approach presented in [1] is used to stabilize the combustion and the robustness of the system against the variation of time lag 3 and pressure exponent γ is considerably improved. |
