将最优控制和人的反应理论相结合，建立了一个计算机化的，预测模型的输入输出跟踪响应的人炮手在高射炮回路。该模型包括各种人为限制的表示，如时间延迟和随机性，这些限制会降低系统性能。该模型通过考虑快速变化的系统动态和任意非随机输入干扰，扩展了早期的手动控制工作。将跟踪误差协方差的模型预测与来自陆军进行的模拟火神防空系统（VADS）实验的人体跟踪数据进行比较。协议是优秀的仰角和方位轴跟踪，在一系列的目标通过从容易到困难。使用一组典型的人类响应限制的人模型输入参数的预测。它的结论是，建模方法可以使用的信心，在武器效能的系统分析研究。
Optimal control and human response theory are combined to develop a computerized, predictive model of the input-output tracking response of the human gunner in an antiaircraft artillery loop. The model includes representations for various human limitations, such as time-delay and randomness, that act to degrade system performance. The model extends earlier work in manual control by considering rapidly varying system dynamics, and arbitrary nonstochastic input disturbances. Model predictions of tracking error covariance are compared with human tracking data from Army conducted experiments that simulated the Vulcan Air Defense System (VADS). The agreements are excellent for both elevation and azimuth axis tracking, over a range of target passes from easy to difficult. The predictions are obtained using a single set of man-model input parameters that are typical of human response limitations. It is concluded that the modeling approach can be used with confidence in a system analysis study of weapons effectiveness.
