This video shows the steps to design a increasing and decreasing counter which toggles after reaching a certain threshold value in Simulink MATLAB - R2019a.
In this video basically it toggles to decreasing counter after reaching to the MAX value and reverts to increasing counter once it reaches to MIN value. In this video, MAX values is assumed to be 5 and MIN value is assumed to be 0. The key concept in designing this counter is to ensure that between the MIN and MAX value the counter retains its flow (i.e. basically the slope of counter is retained). So, if a counter is increasing it will continue with increasing part unless it reaches to MAX value. Similarly, if a counter is decreasing it will continue the decreasing order until it reaches the MIN value. To get the increasing or decreasing information a derivative block is used in the model which gives the slope of the model.
In this video pure Simulink blocks are used to implement the concept and no other features of MATLAB like Stateflow or MATLAB code has been used.

How can i implement the same concepts but except of reaching a threshold ..it switches from increasing to decreasing based on a push button ?

@ProgrammerWorld 6 месяцев назад

Assuming the PUSH button action will be from an App's GUI (designed in App designer). Then in that case, just set a base workspace variable value in the callback method of the Push button. In Simulink, use IF ACTION SUBSYSTEM block based on this variable's value to switch/ toggle between the increasing and decreasing counter. Hope it helps.

@@ProgrammerWorld can you further explain how to implement the if action subsystem ?

@ProgrammerWorld 6 месяцев назад

@ElafEbdah Will try to make a tutorial on this soon.

I couldn't stairs output which you have shown. instead of that i got slope output.

How to design same without using derivative block

@ProgrammerWorld 6 месяцев назад

Simulink models simply translates a mathematical equation into block diagrams. Now, for a counter, the mathematical equation is >> Y(t) = Y(t-1) + 1; %Basically increasing the value by 1 in each time step 't'. So, to get Y(t-1), we will need delay block. The only other option would be to use CLOCK or Signal Editor (Signal Builder in previous versions) blocks. However, in these blocks the signal for the entire duration would need to be manually orchestrated and hence, not recommended.
