Modelica.Blocks.Tables.CombiTable1Ds

Question

我想将 Combotable 的输出连接到下面文件中的信号电流源，但这是不可能的，因为 table 的输出是数组但电流源的输入是真实的。感谢有人帮助我。

model TableTest
  Modelica.Blocks.Tables.CombiTable1Ds combiTable1Ds1(table = [0, 0; 1, 1; 2, 4; 4, 16])  annotation(
    Placement(visible = true, transformation(origin = {-4, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  Modelica.Blocks.Sources.Constant const(k = -5)  annotation(
    Placement(visible = true, transformation(origin = {-46, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  Modelica.Electrical.Analog.Sources.SignalCurrent signalCurrent1 annotation(
    Placement(visible = true, transformation(origin = {48, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 90)));
equation
  connect(const.y, combiTable1Ds1.u) annotation(
    Line(points = {{-35, 0}, {-17, 0}}, color = {0, 0, 127}));
  annotation(
    uses(Modelica(version = "3.2.3")));end TableTest;

在您的情况下，CombiTable1Ds其向量中只有一个输出。只需使用以下命令将其连接到当前源：

connect(combiTable1Ds1.y[1], signalCurrent1.u);

如果使用 Dymola，则在绘制连接时选择y[1]而不是默认y[:]
