Can I make the sampling time changeable during the simulation?
For example, I want the sample time to be 0.0005 in the beginning and then change it to 0.00001 after 3 seconds.
Dear Hussein Sharadga
this depends on the Simulink Block type that you are using within your Simulink model. For more information, you can refer the following link from Mathworks:

Best wishes.
Dear Hussein
I suggest you look to the attached file.
1- use two sum blocks.
2- change the sample time for each one as you need.
3- add a delay block to one of them.
4- connect the outputs of the sum blocks to switch.
I hope that can help you.
good luck
Dear Wasim Soliman and Marwan
Thank you so much. I am working on MPPT for PV system and am using continuous simulation type. I noticed that the controller changes the duty cycle every 0.00001 seconds. I found that the sampling time equals to 0.5*(frequency^-1). Frequency is 50000 which is the frequency of the PWM generator.
0.5* (50000^-1) =0.00001 second
I need to change the sampling time during the simulation. For example, the sampling time will be smaller when there is a sudden change in the operating condition (0.000005 seconds).
Thanks a lot.
