基于操作员感觉的训练仿真器建模方法

训练仿真器的基本要求是使受训者得到与操作实机时相一致的动静态感觉。一个好的数学模型的建立是实现感觉匹配的关键。提出了一种基于感觉的建模方法,其基本出发点是把操作感受看作对象响应的“快慢”、“趋势”、“振荡感”和恰当的组合,它们是由数学模型的零极点及其分布所决定,通过一定的模型结构和模型参数选择的方法,使数学模型的零极点及其分布和感觉相匹配。给出建模的具体步骤和实例,仿真结果证实模型与被仿真对象不仅“快慢”、“趋势”、“振荡感”一致,而且二者响应曲线非常接近。

Modeling Method Based on Feeling for Training Simulator

The basic requirement of the training simulator is to give trainees the similar dynamic and static feeling as real system does. The key to matching the simulator and real system is its modeling. A method based on feelings for training simulator is introduced. The basic view of the method is briefly described as follows. Operating feelings are regarded as "rising speed", "rising trend","oscillatory feeling" and their combination. The feelings depend on zeroes, poles and their distributions of the mathematical model. The method makes the zeroes, poles and their distributions match the feelings by given model structure and technique to choice parameters. Modeling steps and sample are given in this paper. The simulation result shows that the feelings such as "rising speed", "rising trend" and "oscillatory feeling" are similar, and the simulation curves are close to each other.
