Hi Manoj,

You  could either use the first link or the second one from MATLAB help section.

Thanks for the reply,

Actually i don't  have that library in my simulink. Is there any other method to find average value. Or else can i copy that blocks from the new version to older version by making some changes in the S functions. 

Hi Manoj,

you should at least have the "to workspace" block, where you can assign your data to a workspace variable. There you can calculate the average value in a m-file or the command window.

thanks @Gergorie It is working.

@ Martin i also thought to use the same way . 

The answer to this question is depending on your switching frequency or ripple frequency. You can use the above mentioned methods, provided you know the frequency of the ripple. Even a simple low pass filter might work as well.

But if you are dealing with variable switching frequency (such like hysteresis current control), then you need an adaptive filter. Try to search keywords like "adaptive moving average filter" and "variable frequency".

simply Integrate it by 1/s block and then divide by signal time(clock) using a division block.

you can connect the continuous signal to  the mean block , its output will be the average value of the signal

Dear  @ Sanjay Sankaranarayanan Sir;

 I have the same question.

How to calculate in m-file or in the command window.

Is there any command or code to do so.
