How to generate a quadratic signal in Simulink ?

Good afternoon,

I am developing a model in Simulink which requires a quadratic signal to be fed as an input for a predetermined period of time. Is there a block in Simulink which allows me to generate a quadreatic signal for any amount of time I define ?

Hi Simon,

What if you try using the block Polynomial (you find it in the section 'Math Operations', in Simulink Library). With that block, you can define the coefficients of the quadratic equation with the clock as input. The block output can be used as input to your model. See image below:
