I'm having a problem getting an inverse laplace transofrm with what, I

think, is a PD controller.

I have a function H(s)P(s), where H(s) is known and P(s) is the input

signal.

I have to get [h(t) CONVOLUTION p(t)], but I'm not able to do

InvLaplace [ s P(s)/((s+1)(s+50))]

because P(s) is unknown. The idea is to have the result in terms of

p(t), p'(t), p''(t), etc.. Does Anyone know how to do this?

Thanks for any help
