How to create custom integral blocks?

Best Answer

See the following example that uses an S-function to implement a continuous limited integrator where the output is bounded by lower and upper bounds and includes initial conditions. You can access the model example using the following command:

>> open_system('msfcndemo_limintm');

And you can look at the internals of the S-function using the following command:

>> edit('msfcn_limintm.m');

You can easily edit the number of input-ports and output-ports of the S-function. Some helpful links are below:

MATLAB: How to change the axis limit when I have 2 axes in the figure

You can use the "yyaxis" and "ylim" commands to set the y-limit for both axes:

>> figure

>> yyaxis left

>> plot(1:10);

>> yyaxis right

>> plot(2:2:20);

>> f = gcf;

>> yyaxis left

>> ylim(f.Children, [0 5]);

>> yyaxis right

>> ylim(f.Children, [5 10]);

MATLAB: How to create a pictogram in MATLAB

You can use "imread" and "image" in a a for-loop to create a pictogram.

>> x = [1 2 3 4];
>> y = [2 4 3 2];
>> im = imread('peppers.png');
>> figure
>> hold on
>> xPos = [1 0.1];
>> yPos = [1 0.1];
>> for i = 1:numel(x)
>>     xPos = xPos + 1;
>>     for j = 1:y(i)
>>         image(xPos, yPos, im)
>>         yPos = yPos + 1;
>>     end
>>     yPos = [1 0.1];
>> end
