摘　　要：火箭炮自动操瞄控制系统包含俯仰/方位两个子系统,两子系统联动时存在轴间耦合非线性关系,并且火箭炮发射时的动力学特性难于建立数学模型。针对上述特性,建立火箭炮自动操瞄控制系统电气模型与虚拟样机模型的耦合模型作为系统仿真的被控对象,并根据系统非线性动力模型对两轴非线性耦合关系进行解耦,进而在此基础上引入滑模控制方法,设计自动操瞄控制系统位置控制器。仿真研究了两轴联动时,两轴非线性耦合关系在解耦状态下的滑模控制特性,结果表明,俯仰/方位两轴非线性耦合关系解耦后进行滑模控制,具有较高的控制精度,对火箭弹发射时产生的力矩绕动具有更强的鲁棒性。The automatic aiming system of rocketc launcher is divided into two subsystems; elevation angle control system and azimuth angle control system. And it is hard to build math model due to its dynamic characteristics. Aiming at the characteristics above,electrical model and virtual prototype model are buit for the automatic aiming system of rocketc launcher,and in the system,the plant decoupling linearization is made on the nonlinear kinetics model. On this basis,a sliding mode control approach is used to design position controller for the precise aiming. Throug the simulation,the control characteristic of the sliding control is studied on the basis of the decoupling linearization. The results show that its control accuracy is very high and the robustness to the disturbance moment is perfect at firing.
