空间智能结构的一种最优调控方法

Optimum Control Method of Intelligent Space Structures

空间智能桁架结构的最优控制问题是一个多目标问题,需要综合考虑结构的强度、位移和控制能耗。通过对目标的归一化处理,以最大目标为最小,提出了实现智能桁架结构的最优调控模型,使控制模型变得简单,从而使结构处于满意的工作状态。用数值方法模拟了控制的效果,算例表明该方法可以使结构的可靠性、精确性和经济性得到统一。

The optimum control of intelligent space truss structures is a multi-objective issue. The strength, displacement of node and energy consumption need to be controlled simultaneously. An optimum control model is presented for intelligent space truss, which takes maximum objective to be minimum by unifying the objective functions. The control model is simple and it can make the structure working at satisfactory status. The control efficiency of the model is simulated by numerical method. The practical examples show that this method can unified the reliability, accuracy and economy of intelligent structures.
