The fuzzy control rule database is built by using sample data to train bp neural network , the control force is calculated by exploiting fuzzy logic in terms of the fuzzy rule database which has been built , and the vibration is decreased by bringing to bear the control force 运用bp神经网络来训练生成模糊控制规则库,然后运用模糊逻辑推理依据已经建好的模糊规则库计算出控制力来对结构进行控制。
In the first methodology , the active control forces are depended on the structural parameters , and the relationship between them is determined by a matrix riccati equation . then the synthesis design variables are kept down to structural design variables 在第一种方法中,结构最优控制力仅依赖于结构设计变量,它们之间的关系可以由一个矩阵riccati方程来确定,从而将综合设计变量缩减为结构设计变量。
The time takenin the filtering and processing of the sensory data for the required control forcecalculation and the transmission of the control force to the actuator or the timetaken by the actuator to produce the required control force may result in inputdelays 输入时滞产生的原因可能是在求取所需控制作用时,常需要时间对传感器数据进行过滤和处理,也可能是执行器需要一定的时间获得所需的控制作用。
In other words , the proportion of controlling forces has been changed which enhances the media reform in a complexion of contradictions and co - operations , making the decisive standardized forces that promote the media system innovation into being 也就是说,社会转型中传媒调控机制的调控主体力量对比发生变化,在相互冲突与合作中促进了传媒的变革,并最终形成推动媒介制度创新的具有决定性的规范力量。
It uses the ideas of the receding horizon and the feedback proofread based on the predictive model of the system response to optimize the objective function and gain the optimal control force , which could minimize the difference between the real output and the desired output 预测控制以系统响应的预测模型为基础,利用滚动优化和反馈校正的思想,对目标函数进行优化得到最优控制力,使对象输出与期望值之间的偏差达到最小。
