摘　　要：简要介绍了稳健性设计的基本原理及其在简易控制火箭弹角稳定系统设计中的应用．田口方法作为稳健性设计的典型代表，它以系统性能稳定、波动最小为优化目标，用特种正交表排列设计参数和误差因素，用方差分析方法分析所得的性能特性值，按照信噪比最大的原则确定系统的最优设计参数和恰当容差．算例根据带控制力矩的六自由度刚体弹道模型，计算某简易控制火箭弹的横向散布作为性能特征值．设计结果表明，该简易控制火箭弹角稳定系统的实际参数与优化参数是一致的．说明这种优化设计方法有良好的实用性．In this paper, the principle of the robust design and the application in the angle stabilization system of the simple control rocket projectiles are brief introduced. The Taguchi method acts as the typical representation of the robust design.With the object of optimum, it pursues the stable performances and low dispersion. The special arthogonal tables are used to row the design parameters and the error factors, the variance analysis methods are used to analyze the performance characteristic values, and then, according to the principle of maximum signalnoise ratio the optimal parameters of the system and suitable tolerances are determined. Based on the six freedom degrees rigid body trajectory model with the control moments, the example of calculating the cross dispersions of the simple control rocket projectiles as the characteristical values is carried out. The results show that, the optimal parameters of the robust design method are justly suit to actual ones of the simple control rocket projectiles. It prove this optimal method to be actual well.
