本文研究现代控制理论在航空火控人—机系统分析中的应用。利用D.L.Kleinman的人模型,在最佳控制和估计理论的基础上,建立了火控系统闭环回路中关于跟踪反应方面歼击机驾驶员的一个计算机化的预测模型。系统动力学包含时变因素,模型还包括了人在执行任务中具有的时间滞后和随机干扰等各种限制。文中提出了火控系统中驾驶员关于信息处理和执行控制特性方面建立预测模型的方法,并在近距离和远距离跟踪条件下进行了数字模拟,计算表明:模型预测和已经了解的驾驶员实际跟踪过程是非常接近的。从对具有不同阻尼系数瞄准具的系统进行模拟的结果也得到与以往关于阻尼系数分析相一致的认识。
This article studies the application of modern control theory in the air-fire control man-machine system analysis. Based on the theory of optimal control and estimation, a computerized prediction model of fighter pilots in tracking response was built up by using D.L. Kleinman’s human model. System dynamics include time-varying factors. The model also includes various limitations such as time lags and random disturbances that people have in performing tasks. In this paper, a method of establishing the predictive model of the driver in the fire control system on the information processing and execution control characteristics is proposed. The numerical simulation is carried out under the condition of short distance and long distance tracking. The calculation shows that the model prediction and the actual driver The tracking process is very close. The results from simulating a system with sights with different damping coefficients are also consistent with previous observations about damping coefficients.
