6.研究结果及其讨论 结果,根据计算,获得了浮选过程的调节参数。为了检查调节参数并对其进行优化,我们使用 Simulink 包。在 Simulink 环境中,根据收到的调节参数构建了一个瞬态过程。同时,对获得的瞬态过程的分析表明,计算出的调节参数提供了调节,但它们的调节时间较长。在这方面,为了优化瞬态,应用了 PID 控制器的内部设置。结果,控制时间减少了,因此,新瞬态过程的质量得到了改善。因此,这些参数被采用为浮选过程 ASC TPNC 的初始设置。

摘要:数字 FIR 滤波用于通过数字输入产生数字输出。数字滤波是数字信号处理最强大的工具之一。由于 VLSI 技术的进步以及数字信号处理器在雷达应用中的使用,FIR 滤波器起着重要作用。数字滤波器能够达到性能规格,而使用模拟实现则极难甚至不可能达到。此外,数字滤波器的特性可以在软件控制下轻松更改。本文简要概述了有限脉冲响应 (FIR) 数字滤波器的基本结构和硬件特性。使用 Simulink、Mat lab 和 Xilinx System Generator 工具,使用 DSP 系统高效设计了 FIR 滤波器。Xilinx 为 DSP 设计提供了各种高质量的先进产品。我们将使用乘法累加器 (MAC) 单元实现数字滤波器,这是在 FPGA 上实现数字滤波器的基本元素。关键词:数字信号处理、数字 FIR 滤波器、Mat lab Simulink、Xilinx 系统生成器。

为了在可接受的仿真时间内获得准确的寿命评估结果,以满足全生命周期设计标准,本文提出了一种基于循环神经网络 (RNN) 的模型来替代 Simulink 模型。首先建立永磁同步发电机 (PMSG) 的平均开关 (AS) 模型和平均基波 (AF) 模型来计算累积损伤。然后,在相同的任务概况下,计算并比较 AS 和 AF 模型的结温、雨流计数和累积损伤。可以看出,AS 模型可以更准确地计算组件的可靠性,因为该模型既考虑了负载变化引起的大热循环,也考虑了基波交流电流引起的小热循环。然而,与 AF 模型相比,它耗费更多时间。为此,提出使用 RNN 模型来替代系统可靠性评估程序中最耗时的部分。借助所提出的模型,与 Simulink 模型相比,可以大大减少所耗时间。最后,通过一个1小时的案例验证了RNN模型的有效性。测试用例的平均绝对百分比误差(MAPE)为0.51%,RNN模型得出结果的时间小于1秒。此外,还实施了一个年度案例来验证RNN模型,全年平均MAPE为0.78%。
