Physical significance of G(s)H(s) in a control system

hello friends,

what is the physical significance of G(s)H(s) in a control system. It of course does not represent the gain of the system. Is this term used only for the determination of Bode Plot frequencies etc ?

How is it related to open loop forward transfer function G(s) of the control system in terms of the physical entity being represented?

regards,
proffy

    This term is the product of open loop gain G(s) and feedback ratio H(s).

    Based on the product function we have here only we can find whether the system is stable or not
