引言模拟计算机的计算精度通常在0.1～0.5％左右,所以变数量范围是最小值的一千倍。在最小值当中所计算的结果含有明显的误差。例如,将空空弹的飞行路线通过模拟计算机进行模拟的情况下,设想当母机发射时与目标间的距离是数千米,飞行终了时与目标的距离(误差距离)为数米左右。空对空导弹通过制导装置不断地修正误差,但这精度决不是很高的。通过模拟计算机对具有这种误差修正电路的系统进 Introduction The computational accuracy of analog computers is usually around 0.1 to 0.5%, so the variable range is a thousand times the minimum. The result calculated in the minimum contains significant errors. For example, in a simulation of an air-to-air flight path simulated by a simulation computer, it is assumed that the distance from the target when the aircraft is launched is several kilometers and that the distance from the target (error distance) at the end of the flight is several meters. Air-to-air missiles continue to correct errors through the guidance device, but this accuracy is by no means high. The system with this error correction circuit goes through an analog computer
