摘要
针对大型捆绑火箭空间模态参数不确定性较大的特点,建立了大型捆绑运载火箭姿态动力学模型,提出了基于反步的自适应增广控制方法,设计了反步控制律,分析了自适应增广控制的机理,并针对弹性参数不确定性进行了仿真。理论分析和仿真结果表明,所提出的基于反步的自适应增广控制对于空间模态参数的不确定性具有很强的适应性。
A novel adaptive augmenting control based on the backstepping control method is proposed for the spatial mode parameter uncertainties of the large strap-on launch vehicle.Firstly,the large strap-on launch vehicle attitude dynamics model of single machine form is established.Then,a backstepping control law is designed,and the mechanism of adaptive augmenting control is analyzed.Finally,the simulations are conducted for elastic parameter uncertainty.Theoretical analysis and simulation results show that the adaptive augmenting control based on backstepping control proposed in this paper has strong adaptability to the uncertainty of spatial mode parameters.
