以 Fixed Time 模式进行交易

Ambitious corporate climate action

Through the 2015 Paris Agreement, world governments committed to curbing global temperature rise to well-below 2°C above pre-industrial levels and pursuing efforts to 以 Fixed Time 模式进行交易 limit warming to 1.5°C. In 2018, the Intergovernmental Panel on Climate Change warned that global warming must not exceed 1.5°C to avoid the catastrophic impacts of climate change.

To achieve this, GHG emissions must halve by 2030 – and drop to net-zero by 2050. We have limited time for action and the private sector has a crucial role to play – 以 Fixed Time 模式进行交易 以 Fixed Time 模式进行交易 every sector in every market must transform. Organizations with science-based targets are already cutting emissions at scale; all businesses must now join them.

Join the companies taking action

We need a race to the top, led by pioneering companies and financial institutions. This will empower peers, suppliers 以 Fixed Time 模式进行交易 and customers to follow suit and drive governments to 以 Fixed Time 模式进行交易 take bolder action.

The change has already begun and action is gaining pace. Over a thousand organizations worldwide are leading the zero-carbon transformation by setting emissions reduction 以 Fixed Time 模式进行交易 以 Fixed Time 模式进行交易 targets grounded in climate science through the Science Based Targets initiative (SBTi).

The SBTi defines and promotes best practice in science-based target setting. Offering a range of 以 Fixed Time 模式进行交易 target-setting resources and guidance, the SBTi independently assesses and approves companies’ targets in line with its strict criteria.

Companies report that adopting a science-based target:

  • Boosts profitability
  • Improves investor confidence
  • Drives innovation
  • Reduces regulatory uncertainty
  • Strengthens 以 Fixed Time 模式进行交易 brand reputation

Companies committed to the Science Based Targets initiative are demonstrating that creating a climate-secure world goes hand-in-hand with successful business operations.

Setting science-based targets supports an ambitious decarbonization roadmap, clarifying the alignment with the Paris 以 Fixed Time 模式进行交易 Agreement, and promotes a global net-zero energy system Ernesto Ciorra Enel Chief Innovability® Officer

以 Fixed Time 模式进行交易

Simulink ® 允许您直接将模块的采样时间指定为数值,或者通过定义采样时间向量以符号形式指定。对于离散采样时间,向量为 [ Ts , To ],其中 Ts 是采样周期, To 是初始时间偏移量。例如,假设有一个离散模型每隔两秒生成一次输出。如果您的基本时间单位为秒,您可以为 SampleTime 参数指定数值 2 ,直接设置离散采样时间。因为偏移量的值为零,所以不需要指定;但您可以在采样时间字段中输入 [ 2,0 ]。

对于非离散模块,向量的分量是符号值,代表采样时间的类型中的一种类型。下表总结了这些类型及其对应的采样时间值。此表还明确了每一种采样时间类型是否为显式,并列出了关联的颜色和注释。 因为 继承的采样时间 是显式的,所以您可以将它指定为 [-1, 0] 或 -1 以 Fixed Time 模式进行交易 。但是,触发采样时间是隐式的;只有 Simulink 可以分配采样时间 [-1, -1] 。(有关颜色和注释的详细信息,请参阅查看采样时间信息。)

例如,假设有一个模型定义了三个采样时间: 1 、 2 和 3 。再假设它引用了一个模型,该模型定义了两个采样时间: 2 和 3 。在这种情况下,以 2 采样率运行的模块在父模型中显示为绿色,在引用的模型中显示为红色。

请注意, Mux 和 Demux 模块只是对运算符进行分组;通过它们传递的信号将保留计时信息。因此,对于从 Demux 模块发出的信号线,如果驱动它们的源模块具有不同的采样时间,它们可能具有不同的颜色。在这种情况下, Mux 和 Demux 模块采用混合颜色编码(黄色),表明它们处理的是多速率信号。

同样,Subsystem 模块如果包含具有不同采样时间的模块,它们也采用混合颜色,因为没有任何一种速率与它们关联。如果一个子系统中的所有模块都按同一种速率运行,Subsystem 模块的颜色将根据该速率来决定。

ex_specify_sample_time

在此示例中,将输入正弦波信号的采样时间设置为 0.1 。目的是获得 0.2 的输出采样时间。 Rate Transition 模块作为零阶保持器。设置采样时间并对模型进行仿真后,生成的模块图如下图所示。(颜色和注释表明这是一个离散模型。)

设置采样时间后的 ex_specify_sample_time

以交互方式指定基于模块的采样时间

在 Simulink 模型窗口中,双击该模块。模块参数对话框随即打开。

采样时间字段中输入采样时间。

点击确定

采样时间字段中输入 0.1 后, Sine Wave 模块的参数对话框如下图所示。

要在整个模型中指定和检查基于模块的采样时间,请考虑使用模型数据编辑器(在建模选项卡上,点击模型数据编辑器)。在输入端口/输出端口信号数据存储选项卡上,将更改视图下拉列表设置为“ 设计 ”并使用采样时间列。有关详细信息,请参阅模型数据编辑器

以交互方式指定基于端口的采样时间

Rate Transition 模块具有基于端口的采样时间。您可以按照以下步骤,以交互方式设置输出端口的采样时间:

双击 Rate Transition 模块。参数对话框随即打开。

输出端口采样时间选项的下拉菜单选项保留为“ 指定 ”。

输出端口采样时间字段中的 -1 替换为 0.2 。

点击确定

以编程方式指定基于模块的采样时间

要以编程方式设置模块的采样时间,请使用 set_param 命令将其 SampleTime 参数设置为所需的采样时间。例如,要将 Specify_Sample_Time 以 Fixed Time 模式进行交易 模型中的 Gain 模块的采样时间设置为继承 ( -1 ),请输入以下命令:

以编程方式指定基于端口的采样时间

要将 Rate Transition 模块的输出端口采样时间设置为 0.2 ,请使用 set_param 命令和参数 OutPortSampleTime :

以编程方式访问采样时间信息

为自定义模块指定采样时间

您可以设计自定义模块,使输入端口和输出端口以不同的采样时间速率运行。有关为 S-Function 指定基于模块和基于端口的采样时间的信息,请参阅 Specify 以 Fixed Time 模式进行交易 以 Fixed Time 模式进行交易 S-Function Sample Times。

确定采样时间单位

由于 Simulink 模型的执行不依赖于一组特定的单位,所以您必须为您的应用确定合适的基本时间单位,并相应地设置采样时间值。例如,如果您的基本时间单位是秒,则您可以将采样时间设置为 0.5 来表示 0.5 秒的采样时间。
