One of the significant difference between the open loop and closed loop control system is that in an open loop system the desired output does not depend on the control action. While in the closed loop system the desired output depends on the control action of the system. The other differences between the open and closed loop system are shown below in the comparison chart.

Open loop and closed loop circuits Open-loop: Pump-inlet and motor-return (via the directional valve) are connected to the hydraulic tank. The term loop applies to feedback; the more correct term is open versus closed "circuit". Open center circuits use pumps which supply a continuous flow. The flow is returned to tank through the control valve''s open center; that is, when the control valve is

Most modern closed-loop CNC systems are able to provide very close resolution of 0.0001 of an inch. Closed-looped systems would, naturally, require more control devices and circuitry in order for them to implement both position and velocity control. This, obviously, makes them more complex and more expensive than the open-loop system. A closed/open comparison is shown below.

Unlike an open loop hydraulic system, fluid does not flow to a reservoir, but flows directly back to the pump (which is why the term “closed loop” is used to describe this type of circuit). Without the benefit of a large reservoir of fluid to dissipate heat, this means the potential for heat generation is more dramatic in closed loop systems. To compensate for this increased risk of
