How to vary offset during simulation

Hello, i need to vary the offset of a 60hz 180V sinewave during the simulation.
How can i do that? I am trying to use Step and Controlled voltage source, but it's not working.
Any ideas?
Thanks

Hi Luiz,
You can include a slider (fomr the section Dashboard in the Library) in the Simulink model, and link it to the SineWave bias. Then you can change the bias during the simulation by moving the slider.

You can include a MATLAB function block with a piece of code to do this change in the time you want. See the screenshot below, where I use the 'Clock' block to ge tthe current simulation time, and when time is equal to 20, the bias is set to 10.
Another good option is to do it with simple blocks. Please read the following post with an example:

So you need to generate V*sin(2*pi*f*t).
There is a block for sin(). Use "Repeating Sequence" or "Repeating Sequence Interpolated" from Simulink Source library where you can specify any time-value pairs.
