Complementary Filter Reset Orientation

Hi all,

I am using the complementary filter block on Simulink to estaimate the Orientation of my IMU. This seems to be working okay. But what I can't seem to figure out is how to reset the Orientation to either no rotation (so as if I start measuring again) or to a specific orientation. Is there a possibility to do this with the Block?

I could do it afterwards, by using a boolean which stores the orientation at the specific point in time I want to reset it and then just rotates the orientation back by that amount, but there must be a better solution for this.

I hope I could explain the problem well enough, but if not, don't hesitate to ask!

Thanks!

@Alexis do you want to change the orientation to different values during the simulation?

Well, yes and no. I have another method of calculating the orientation that is much more precise, but which I only do every couple of minutes. So the goal would be to update the current orientation with the one I calculated precisely every couple of minutes and then continue integrating from that one using the IMU until I have a new precise measurement.
