@Preben Alsholm this should be a great help in proving observability for my system for a region of inputs and initial states. Since most of the equations in my Grammian have the same structure as this equation.

Thanks for the input Preben! This should help me solving the system at least numerically. However I'm still not sure if Maple can handle the integration of this function, because it will be quite a difficult equation I guess.
