Press the space bar to automatically zoom to display all fit to view; select a module and press enter to double-click

Select some options in "Display- Blocks -Tool tip options", and automatically display related information when the mouse is placed on the block

Mux block display format

Create subsystemSubsystemMethod: ① First build the structure and select ctrl+g or "Diagram-Subsystem & Model Reference-Create subsystem from selection" or right-click "create subsystem from selection", this method does not need to add input and output ports, after ctrl+g Automatically added; ② You can also drag a subsystem from the "Simulink – ports & subsystems" in the library browser to the model and then edit it.

After creating the subsystem, you can proceedEncapsulation mask: Right-click subsystem "mask – create mask" or shortcut key ctrl+m;
(1) After creating the subsystem, double-click the frame of the subsystem to enter the view subsystem. If you encapsulate and add parameters, double-click to pop up a dialog box to change the parameter value.
(2) After packaging and adding a callback function by right-clicking "properties-callbacks", double-clicking does not bring up a dialog box nor enter the viewing subsystem, but executes the callback function. For example, the production process of the "variable initialization" box in slcp is:

The constant block display is shown in the figure, because the length is too small, and the number cannot be displayed completely; other blocks also have different display effects due to the size relationship.

Press and hold ctrl to separate the branch line from a connection line; right-click on a block in the model library and select "open xxx library" to display the block in a window

Custom package graphic display (reveals why cart and pole dynamics in routine slcp can be displayed as a custom graphic); icon can be set to display text, read pictures, draw pictures by own plots, etc., display calculation results, etc.

Set the overall properties of the model, such as running and loading when the model is opened, right-click on the model blank space-Model Property

Other understanding about the self-contained routine sclp: (2015/12/16) There are only two m files, which are initcp.m (registered to run when the model is started and run when the variable initialization subsystem is double-clicked) and animcp.m .

global AnimCpFigH AnimCpAxisH% is unclear at present, it may be used for animcp
 winName = bdroot(gcs); %bdroot is Matlab's own function, used to return the name of the front-most Simulink model
fprintf('Initializing ''fismatrix'' in %s...\n', winName);
 fismatrix = readfis('slcp.fis'); %Here the slcp.fis file is defined in advance; instead of being regenerated
fprintf('Done with initialization.\n');

Implement package array (matrix) variables: After adding variables to the subsystem (ctrl+m is edit mask), double-click the subsystem and enter the variable value with brackets, such as "[0,0,0,0] ", and then initialized in the edit mask, otherwise an error is reported

Simulation animation

Regarding the simulation time, the displayed time should be seconds, But if you don’t need so much time in the simulation calculation (for example, there is no complicated algorithm for solving differential equations, etc.), the calculation will be stopped; and for a simulation like slcp, setting 1000s may completely master the simulation performance, you can think This is an infinite time.
