Input different DC voltage at different time Simulink

How to input different voltage as time goes by.

For instance, At 0 to 9seconds, the input voltage is 10V. After 1 second delay, 10seconds to 19seconds, the input voltage is 20V for example.

Does this possible in simulink matlab?

hey i m also looking for same if you had solution. share it

There are many options to do this in Simulink and can be found at:

One simple way would be to create a vector containing the voltage values at the required time sequence and use a From Workspace block.

If you are using SimPowerSystems, what you need is the Controlled Voltage Source, then you feed a signals as described by Nirmal.

I'm not familiar with the Power Systems modeling domain, but it seems like the DC Voltage Source from the SimPowerSystems library might be a good starting point for you.
