摘要: 利用分布式处理机及网络技术对机载机电设备进行综合控制管理是机载机电设备发展的一大趋势,其中如何分配机载机电系统的控制管理任务,使系统风险均衡,达到提高系统可靠性、安全性的目的是综合控管课题的关键技术之一,其实质上是一个优化组合问题.本文针对该问题,提出了适用于机载机电设备综合控管系统的任务分配准则和目标函数,利用遗传算法,寻求任务分配的最优策略,达到了较好的效果.Abstract: It's a trend that the aircraft onboard machine-electronic equipment is controlled and managed integrated by using the distributed processors and the network technology. How to assign the tasks of control and management to the distributed processors to balance the risk factor of system is the key technology in the problem of integrated control and management. It's also the main technology to improve the system reliability and safety. The fact is a combinatorial optimization problem. In this paper, the task assignment rules and object function are presented. The best strategy of the task assignment is searched by using the genetic algorithm, and the results are illustrated.
