拖靶的垂向运动传递函数是设计拖靶高度控制系统的基础.由于拖靶系统的复杂性,难以直接从飞行动力学模型中求解传递函数.解决的方法是以拖靶为研究对象,通过受力分析,得到拖靶的垂向运动微分方程,再根据线性系统理论中的小扰动假设,就能够从静态出发,得到动态特性.在拖靶的设计阶段得到的传递函数,为拖靶高度控制系统的设计提供了定量分析的手段,对其设计工作意义重大.

The vertical motion transfer function of towed target is the base of designing height control system. Because of the complexity of the towed target system, it is difficult to directly solve the transfer function from the flight dynamics model. It can be sovled by researching towed target. It get to the differential equation of motion target vertical through the analysis of force. According to the assumption of small perturbation theory in the linear system, we can get dynamic characteristics from static. The transfer function from the design stage provides a quantitative analysis method for the design of height control system of target. It has a great significance for the design of the towed target.
