基于反演法的单兵制导火箭弹仿真研究

为满足单兵火箭弹体积小、质量轻、低成本的设计要求,建立了由两路舵机控制的俯仰、滚转双通道单兵火箭弹模型,差动进行滚转控制,同向偏转进行俯仰控制,应用反演法对俯仰通道控制器进行设计,并与PID控制进行对比分析.同时,为了与三通道控制作对比,引入偏航控制.研究结果表明,该控制器的解耦性能优于PID控制,具有良好的跟踪效果....

Simulation of Individual Guided Rocket Based on Inversion Method

In order to meet the design requirements of small size,light weight and low cost of single soldier rocket,the model of pitch and roll dual-channel individual rocket controlled by two steering engines was established,and roll control by differential,pitch control by deflection in the same direction. The inversion method was used to design the pitch channel controller,and compared with PID control. To compare the proposed method with three-channel control,the yaw control was introduced at the same time. The results show that the decoupling performance of the controller is better than PID control,and the controller has good tracking effect. In the case of aerodynamic parameter perturbation,it can maintain certain robustness and anti-interference ability. The inversion controller can meet the control requirements of dual channel signle solidier rocket. Compared with the three-channel control,the proposed two-way actuator control model has more flexible internal layout,and it is more suitable for small-caliber and low-cost requirements of individual rocket.
