DIFFERENCE BETWEEN CLOSED LOOP AND OPEN LOOP …

Heat generation in open loop hydraulic system will be less but as large volume of fluid will be required in case of open loop system, hence size and weight of open loop system will be more as compared to close loop system.

Designing closed-loop circuits for stability | Hydraulics …

 · For a highly stable closed loop with a well-damped output response, the phase margin should not be less than 45°. This means that the loop phase lag at the gain crossover frequency should not exceed 135°. Phase margins considerably greater than 45° also can result in a heavily over-damped closed-loop output response.
