Smooth step changes in simulink

Hi

Can you help me with implementing smooth step changes in simulink similar to these figures?

What do you mean by smoothening?What do you expect at the output? In a control system point of view the wavefroms looks to be the response from an LTI system with Pi controller. Can u represent your model?

You said similar to this, but what do you want exactly?

Answer 1

using a low pass filter should produce the result you wanted..

My question is can I manually build such a signal in simulink?It's somewhat similar to step changes but with smooth edges.
