Output feedback control for energy-saving asymmetric hydraulic servo

When an asymmetric hydraulic cylinder moves symmetrically back and forth, the pressure and flow in the two chambers differ a lot, resulting in huge energy loss.

How do accumulators improve system performance?

An accumulator can compensate for temperature-related pressure differences in a closed hydraulic system. Accumulators minimize the effect of pressure changes by adding or reducing the amount of fluid in a circuit. Bladder and diaphragm accumulators have virtually instantaneous response and can quickly supply fluid to fast-acting servo and
