I have to design a robust Hinf controller for an LTI system which has a known input  besides disturbances and control inputs. (this input is not disturbance or control input)

{xdot}=[A]{x}+[B1]{m}+[B2]{w}+[B3]{u}

{z}=[C1]{x}

{y}=[C2]{x}

"{m}" is a known input vector (measurable), "{w}" is disturbance vector and "{u}" is a control input vector.

How can I design this controller in a MATLAB m file? ({m} is not supposed to be considered as a disturbance or control input)
