【摘要】 提出两种传感器优化配置准则:基于极点配置的准则和基于最优控制的准则,给出了传感器优化配置问题的数学模型。土木工程结构传感器配置问题属于0-1规划问题,不能通过用目标函数对优化变量的导数为零的条件来求解,本文采用枚举法和遗传算法对该问题进行了研究,并对遗传算法进行了改进。更多还原

【Abstract】 In this paper, two optimal placement laws of sensors are presented: based on pole assignment and optimal control law respectively. The mathematical model of optimal placement for sensors is also given. In the field of civil engineering structures, it has boiled down the optimal placement problem of sensors to 0-1 program problem, we can not utilize the condition that the differential coefficient of the performance function with respect to the optimal variable equals to zero. Enumeration and genetic algorithms are applied to solve the problem and improved genetic algorithms are proposed.更多还原
