Title The spin artillery missiles stability and control
analysis and simulation
Abstract
Spin artillery missiles is one of the main research directions in the field of modern weapons,its stability and maneuverability research is an important part of the overall design.The graduate design research dynamic characteristics of spin missiles,And the establishment of a spin missile dynamics model thus obtained through linearization of perturbation equations of motion, and then strike a transfer function.In an example of a spin-missile,Stability analysis use computational parameters missiles, and through theoretical analysis to verify the various kinetic coefficients are different for dynamic stability affect.Designed the damping circuit to adjust underdamped system,and then contrast underdamped and join damping circuit.When giving the system a step deflection control mechanism, the system angle of attack, roll angular velocity output response chart,and in order to analyze the system handling, through comparative analysis shows that a reasonable choice damping control mechanism can improve the quality of transition.
Combined with the speed determined by the classical method to determine the missile speed range,And verify that there is an optimal speed missile conclusion thus get the optimal speed of a spin-projectile.Finally, the dynamic characteristics of the missile several requests summarized and analyzed, draw relevant conclusions.
Keywords The spin artillery missiles , stability, Maneuverability, Damping circuit, Rotational speed

1．1 背景及意义
自上个世纪开始，对于自旋导弹的研究逐步开始进展，逐渐深化形成了系统的理论体系。在相关的理论指导下，自旋导弹的研究得到长足发展，相关技术也日趋成熟。1985年美国开始研制MGM-51A橡树棍炮射导弹，采用红外指令制导；为了提高主战坦克的远距离精确打击能力和反直升机能力，苏联在20世纪60年代开始研制炮射导弹；在20世纪90年代的时候，很多西方国家也研制出了应用不同制导方式的自旋导弹。目前，处于世界领先地位的是俄罗斯的自旋炮射导弹,因此俄罗斯成为世界上成系列开发并在主战坦克上大量装备炮射导弹的唯一一个国家[1]。
