在观测目标相当遥远及准单色观测条件下，根据光学综合孔径光学传递函数以及傅里叶变换性质建立了一个简化的像面干涉光强分布数学模型，此数学模型的物理含义符合光学综合孔径成像观测的实际情况；根据光学综合孔径瞳面干涉条件，在光学综合孔径像面干涉数学模型的基础上得到瞳面干涉的数学模型。

Considering just-in-time production, the mathematical model of flexible job-shop schedulingfor bi-objective is established. To solve the model, a genetic algorithm is developed. In this algorithm, a two-row chromosome structure is presented because of the special point of the model. At the same time, AOV network is applied to decode and compute the fitness function. Then selection, crossover and mutation operator of the genetic algorithm are designed. Finally, an example of job shop scheduling is shown.

Finally, based on the studies above, the characteristics of pantograph/catenary are analyzed and the active pantograph is modeled. By using the linear quadratic optimal control law, the design objective is to minimize the performance index, which is a function of the state variables representing the pantographs dynamic characteristic and the active control force. The control system is designed considering the complete state feedback.

最后，在此基础上，分析了受电弓／接触网系统的工作特点，建立了受电弓主动控制系统的数学模型，利用线性二次型最优控制策略，以给定性能指标为最小值为设计目标，性能指标为表征受电弓动力学特性的状态变量和主动控制力的函数，考虑了完全状态反馈的情况，进行了控制系统的设计。
