给出了一种目标可用信息较少情况下的空基助推段拦截中制导律设计方法。该方法首先结合空基助推段拦截的特点,根据平行接近法的思想,将纵向平面内的中制导律设计问题转化成为如何控制惯性坐标系下纵向平面内弹目相对高度差趋于零并保持住的问题,并且建立了相应的输入-输出模型;其次,采用自抗扰控制器对因目标可用信息较少而导致的模型中的不确定项进行估计和补偿,求得所需的指令过载,并在自抗扰控制器设计过程中,说明了一些参数的调节方法;最后,通过仿真验证了文中制导律的可行性。
A guidance method design method for space-based boost segment interception is given in the case of less available target information. According to the idea of parallel approach, this method transforms the design problem of mid-level guidance in the longitudinal plane into how to control the relative height difference of the missiles in the longitudinal plane to zero in the inertial coordinate system Hold the problem, and set up the corresponding input-output model. Secondly, the ADRC controller is used to estimate and compensate the uncertain items in the model due to the less available information of the target to obtain the required instruction Overload, and in the ADRC controller design process, illustrates some of the parameters of the adjustment method; Finally, the simulation verified the feasibility of the guidance law.
