Matlab模块From Workspace使用数据类型说明

Matlab原文连接：Load Data Using the From Workspace Block

模型：

从信号来源的数据：

timeseries 数据：

sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);simin = timeseries(data,time);

 timetable 数据：

sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);secs = seconds(time);
simin = timetable(secs,data);

struct 数据：

Struct的必须得有一个time域和Signals.values域，否则不认出来。

clear simin;sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);simin.time = time;
simin.signals.values = data;

array 数据：

第一列必须是时间，第二列是数据。

sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);simin = [time,data];

加载Bus数据：

Bus 数据：下面是Bus元素定义和Bus(SinBus与SinsoldBus类型)里面包含关系

elems(1) = Simulink.BusElement; %必须有一个Simulink.Bus元素
elems(1).Name = 'Sine';% 必须得有元素名称
elems(2) = Simulink.BusElement;
elems(2).Name = 'BigSine';
SineBus = Simulink.Bus;%创建Bus，并将元素幅值给Bus元素。
SineBus.Elements = elems;clear elems;
elems(1) = Simulink.BusElement; % 创建Bus数据类型
elems(1).Name = 'SineBus';
elems(1).DataType = 'Bus: SineBus';
elems(2) = Simulink.BusElement;
elems(2).Name = 'Cosine';
SinusoidBus = Simulink.Bus;
SinusoidBus.Elements = elems;

Bus里面的元素都是时间序列

% Create workspace data for bus
clear busin
sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);
cosdata = cos(2*pi/3*time);
ampdata = 2*data;busin.Cosine = timeseries(cosdata,time);
busin.SineBus.Sine = timeseries(data,time);
busin.SineBus.BigSine = timeseries(ampdata,time);% Create Simulink.Bus object to define bus hierarchy
elems(1) = Simulink.BusElement;
elems(1).Name = 'Sine';
elems(2) = Simulink.BusElement;
elems(2).Name = 'BigSine';
SineBus = Simulink.Bus;
SineBus.Elements = elems;clear elems;
elems(1) = Simulink.BusElement;
elems(1).Name = 'SineBus';
elems(1).DataType = 'Bus: SineBus';
elems(2) = Simulink.BusElement;
elems(2).Name = 'Cosine';
SinusoidBus = Simulink.Bus;
SinusoidBus.Elements = elems;

Partially specified 数据 ： 和上面对比只是cosine没有数据而已。

% Create workspace data for bus
clear busin
sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);
ampdata = 2*data;clear busin
busin.Cosine = [];
busin.SineBus.Sine = timeseries(data,time);
busin.SineBus.BigSine = timeseries(ampdata,time);% Create Simulink.Bus object to define bus hierarchy
elems(1) = Simulink.BusElement;
elems(1).Name = 'Sine';
elems(2) = Simulink.BusElement;
elems(2).Name = 'BigSine';
SineBus = Simulink.Bus;
SineBus.Elements = elems;clear elems;
elems(1) = Simulink.BusElement;
elems(1).Name = 'SineBus';
elems(1).DataType = 'Bus: SineBus';
elems(2) = Simulink.BusElement;
elems(2).Name = 'Cosine';
SinusoidBus = Simulink.Bus;
SinusoidBus.Elements = elems;

array Buses 数据：

直接是一个Bus数组。

% Create workspace data for bus
sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);
cosdata = cos(2*pi/3*time);
ampdata = 2*data;bus1.Cosine = timeseries(cosdata,time);
bus1.SineBus.Sine = timeseries(data,time);
bus1.SineBus.BigSine = timeseries(ampdata,time);bus2.Cosine = timeseries((cosdata-1),time);
bus2.SineBus.Sine = timeseries((data-1),time);
bus2.SineBus.BigSine = timeseries((ampdata-1),time);busin = [bus1,bus2];% Create Simulink.Bus object to define bus hierarchy
elems(1) = Simulink.BusElement;
elems(1).Name = 'Sine';
elems(2) = Simulink.BusElement;
elems(2).Name = 'BigSine';
SineBus = Simulink.Bus;
SineBus.Elements = elems;clear elems;
elems(1) = Simulink.BusElement;
elems(1).Name = 'SineBus';
elems(1).DataType = 'Bus: SineBus';
elems(2) = Simulink.BusElement;
elems(2).Name = 'Cosine';
SinusoidBus = Simulink.Bus;
SinusoidBus.Elements = elems;

struct 和 Bus 区别和相同点：

数据类型	类型	fiel有要求	timeseries	可以多个
Struct	不需要定义类型	fiel必须是time与signals.values	否	否
Bus	需要定义Bus类型	无要求	是	是

注释：加载数组数据：

% Define simin variable for Signal From Workspace block
sampleTime = 0.01;
numSteps = 1001;time = sampleTime*[0:(numSteps-1)];
time = time';data = sin(2*pi/3*time);simin = timeseries(data,time);% Define bus object for Bus From Workspace block output data type
elems(1) = Simulink.BusElement;
elems(1).Name = 'Sine';
elems(2) = Simulink.BusElement;
elems(2).Name = 'BigSine';
SineBus = Simulink.Bus;
SineBus.Elements = elems;clear elems;
elems(1) = Simulink.BusElement;
elems(1).Name = 'SineBus';
elems(1).DataType = 'Bus: SineBus';
elems(2) = Simulink.BusElement;
elems(2).Name = 'Cosine';
SinusoidBus = Simulink.Bus;
SinusoidBus.Elements = elems;% Define bus data for busin variable
cosdata = cos(2*pi/3*time);
ampdata = 2*data;clear busin;
busin.Cosine = timeseries(cosdata,time);
busin.SineBus.Sine = timeseries(data,time);
busin.SineBus.BigSine = timeseries(ampdata,time);
