煤矿节能减排多目标优化研究
针对传统煤矿节能减排优化模型选取的目标函数比较单一的问题,构建了涵盖经济效益、能源消耗、污染物排放量等目标函数的煤矿节能减排多目标优化模型,并应用基于改进的蝙蝠算法寻找3个目标函数之间的优化解,实现了经济效益最大化、能源消耗最低化、污染物排放量最少化的优化结果。仿真结果表明,相比于PSO-E、NSGA-II算法,改进的蝙蝠算法能够在较短的迭代步数内获取较高的个体适应度,且能够实现较佳的多目标优化结果,符合节能规划的目标需求。(Aiming at the problem that the objective function of the traditional coal mine energy saving and emission reduction optimization model is relatively simple, the multi-objective optimization model of coal mine energy saving and emission reduction is constructed, which covers economic benefit, energy consumption and pollutant emission. And the optimized solution is used to find the 3 target functions based on the improved bat algorithm, and the economy is realized. The optimization results of maximizing efficiency, minimizing energy consumption and minimizing pollutant emissions are achieved. The simulation results show that, compared with the PSO-E and NSGA-II algorithms, the improved bat algorithm can obtain higher individual fitness within a shorter iteration step, and can achieve better multi-objective optimization results, which is in line with the target demand of energy saving planning.)

中文摘要
正交频分复用( OFDM , Orthogonal Frequency Division
Multiplexing)是当前一种非常热门的通信技术。它即可以被看作是一种
调制技术,也可以被看作是一种复用技术。由于它具有抗多径衰落和频谱
利用率高的特点,因此被广泛应用于高速数字通信领域,比如应用于IEEE
802.11a无线局域网(WLAN)的物理层等等。
我的毕业设计的核心任务是:采用 FPGA 来实现一个基于OFDM 技术
的通信系统中的基带数据处理部分,即调制解调器。其中发射部分的调制
器包括:信道编码(Reed-Solomon 编码),交织,星座映射,FFT和插
入循环前缀等模块。我另外制作了相应的解调器,可以实现上述功能的逆
变换。
另外,我还对OFDM技术, IEEE 802.11a的标准文献,基于Simulink
的 OFDM 模型和仿真,ALTERA 公司的技术和 IP Core 的使用等方面进
行了研究。这些在文章中都有体现。
(Abstract
Orthogonal frequency division multiplexing (OFDM, Orthogonal the Frequency Division,
Multiplexing) is a very popular communication technology. It can be seen as a
Modulation technique can also be seen as a multiplexing technique. Because of its resistance to multipath fading and spectrum
High utilization characteristics, and is widely used in high-speed digital communications, such as used in IEEE
802.11a wireless LAN (WLAN) physical layer.
The core mission of my graduation project: FPGA to implement a technology based on OFDM
Communication systems in baseband data processing part, ie the modem. These emission part of the modulation
Includes: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and interpolation
Into the cyclic prefix modules. I also produced a corresponding demodulator can achieve the inverse of the above functions
Transformation.
In addition, OFDM technology, the IEEE 802.11a standard literature, based on Simulink
