为了使导引头伺服控制系统各参数达到最优,提出了一种多参数优化设计方法。文中采用MDO技术,在ISIGHT软件环境下集成导引头多体动力学模型和控制系统模型,以时间误差积分(ITAE)作为优化目标,利用多岛遗传算法(MIGA)完成了对导引头伺服控制系统各参数的优化。仿真结果表明,采用该方法能够使导引头伺服控制系统具有更好的性能指标,具有很好的应用前景。

In order to realize optimization of all parameters for control system of missile seeker, a multi-parameter design and optimization method was proposed. With the technology of MDO, the associated model of mechanical system and that of control system of seeker were integrated based on ISIGHT, and time-error integral (ITAE) was adopted for optimization, parameter optimization was carried out for control system of seeker using multi-island genetic algorithm. The results of simulation demonstrate that performance of control system of seeker has been improved by this method, which shows that this method is promising for application.
