    Hi Folks,

    I have build a small hydraulic system consisting of a hyrdaulic pump, and an ideal flow metre using the sim hydraulics toolbox. I want to find the transfer function of the hydraulic pump. I have tried using the "linmod" command and then changing this from state space to a transform function but it returns a 12th order system I`m pretty sure it is only a single order system. I have attached the simulink circuit I`m using and some of the proecdures I`m following to try get the transfer function. Any help on how I might be able to get the transfer function would be great.
