| 摘要炮射导弹就是将精确制导技术与常规火炮系统进行有机结合，在保留了原有系统反应快、火力猛等特点的前提下，增加了其作战半径，提高了导弹的命中精度。炮射导弹是一种高新技术炮弹，它使火炮这类间接瞄准杀伤武器具备远距离精确打击能力，成为当前兵器领域的重点研究方向。制导技术在弹体上的应用，使得炮射导弹对于外界自然因素有着较强的抗干扰性，从而提高了弹丸的命中概率和杀伤效果。采用过载控制技术，设计炮射导弹自动驾驶仪，采用牛顿力学方法建立了飞行器动力学建模，采用“小扰动”假设得到了线性化模型，建立了基于过载的飞行器控制回路数学模型，采用PID设计过载跟踪控制回路，并进行了仿真，仿真结果上升时间小于0.1秒，超调量小于10%，跟踪误差小于5%，满足性能指标。9014 关键词 炮射导弹 纵向过载 PID控制 毕业设计说明书（论文）外文摘要 Title Design And Simulation On Controller Of Vertical Overload Of Artillery Missile Abstract Artillery missile is the combination of precision-guided systems and conventional artillery systems. In this way, not only retain the original system’s fast response and fierce fire, but also increase the long-range of resistance capability and the accuracy of the missile. Artillery missiles are a high-tech projectile. It give long-range precision strike capability to the indirect targeting anti-personnel weapons and becomes the focus of the weapons-research.It is the Guidance technology on the missile makes that artillery missiles have a strong anti-interference against the external natural factors, thereby increasing the hit probability and the killing effect of the projectile. Overload control technology is used to design artillery missile autopilot instrument. Newtonian mechanics is used to build a vehicle dynamics model. "Disturbance" is the linear model’s assuming. Above all, a mathematical model of the control loop based on the aircraft overload can be established.Overload tracking control loop is designed by PID, and a simulation is completed. The simulation results show that the rise time is less than 0.1 seconds, the overshoot is less than 10% and the tracking error is less than 5 %. The overload tracking control loop suffices the performance indicators.
