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?

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.
