战术导弹垂直发射控制的输出解耦变结构方法研究

战术导弹垂直发射时需要姿态快速机动 ,这造成了在姿态调过程中导弹呈现较严重的非线性和耦合特性。针对垂直发射时系统的要求和特点 ,利用输入输出解耦变结构控制方法 ,研究了战术导弹垂直发射姿态调转的控制问题。首先结合垂直发射的具体特点 ,建立控制系统非线性数学模型 ;然后利用输入输出解耦变结构控制方法 ,进行导弹垂直发射姿态调转的控制系统设计 ,得到了具有良好鲁棒性的非线性控制律 ;最后通过仿真验证了该控制律的有效性

Variable-Structure Control of Vertical Launching Missile Based on Output Decoupling Method

This paper, based on the output decoupling and variable structure control theory, deals with the angle attitude maneuver control of vertical launching tactical missile. Firstly a nonlinear simulation model is established according to the features related to the vertical launching missile. Secondly a nonlinear control law which has a good robustness and meets the required precision is proposed to solve the nonlinear coupling, fast attitude maneuver and parameter perturbation of a nonlinear simulation model for vertical missile launching control. Lastly numberical simulations prove that the presented law is effective.;
