Johnson提出的干扰利用控制理论将应用在寻的导弹的控制中。尽管与控制系统设计有关的非控制输入量通常都看成是有害的,但是,诸如风、地球引力和目标机动这样一些干扰却可以有效地利用于控制目的的实现。在导弹单平面拦截机动目标的问题中,运用最优干扰利用方法所提供的控制性能将远远优于不考虑扰动波形结构的线性二次控制器得到的性能。 Johnson’s theory of interference and utilization control will be applied in the search of missiles. Although uncontrolled inputs related to control system design are generally considered detrimental, some disturbances such as wind, gravitational forces, and target maneuvers can be effectively utilized for control purposes. The control performance provided by the optimal interference utilization method is far superior to that obtained by the linear quadratic controller without considering the disturbance waveform structure in the single-plane missile interception maneuvering target.
