Hello,

I am writing up my PhD at the moment, and I was hoping someone would be able to confirm some Laplace transform techniques that I have been
working with.

My thesis is on self-organising fuzzy logic control and for the past month and a half I have been trying to replicate experiments published by the original creator of the self-organising fuzzy logic controller [1], so as to compare the original work with my own.

The original author's experiments use a transfer function

X(s)= (0.00375/((s+0.15)

where U is the controller input to the system and X is the system output.

multiply it by 1/s and then get the inverse Laplace transform, am I on the right track?

I have used Maple to calculate this and the resulting equation I am using to graph my system is x(t)=U[0.1-0.25

Any help with this would be greatly appreciated, as I have been going round in circles for the past few weeks trying to figure it out, I just need someone to confirm I'm going in the right direction.

Thank you for your time, Ann
