为了减小压心不确定性对质量矩控制的影响,提高活动质量块对系统的控制能力,本文推导了飞行器姿态配平角与压心偏差的关系,分析了压心系数偏差对飞行器控制性能的影响,给出了压心最大容许偏差范围的解析表达式,然后针对压心偏差对飞行器的影响进行了仿真计算,并在此基础上分析了压心测量偏差对质量矩控制飞行器总体参数的要求,提出了几种减小压心不确定性对飞行器控制性能影响的结构布局优化方法。结果表明:对于静稳定导弹,将径向滑块的滑道配置在飞行器的前鼻部,根据任务指标合理地设计各滑块的偏移量等措施都可以减小压心不确定性对质量矩控制的影响。
In order to reduce the influence of the uncertainty of the pressure heart on the mass moment control and improve the control ability of the moving mass on the system, this paper deduces the relationship between the attitude balance angle of the aircraft and the deviation of the pressure center and analyzes the influence of the deviation of the pressure center coefficient on the control performance of the aircraft The analytical expressions of the maximum allowable deviation range of the pressure heart are given. Then the impact of the pressure deviation on the aircraft is simulated and the requirements of the mass moment control aircraft overall parameters by the pressure measurement deviation are analyzed , Several structural layout optimization methods are proposed to reduce the influence of uncertainty of pressure heart on the control performance of aircraft. The results show that for statically-stabilized missiles, the slide of the radial slider is arranged on the front nose of the aircraft, and the measures such as the offset of each slider can be reasonably designed according to the task index can reduce the uncertainty of the pressure heart against the mass Moment control effect.
