Abstract: A new type of energy saving electro hydraulic control
system for multiple actuator compounded control is put forward.
Switchmode hydraulic power supplies are applied in the driving and
control of the hydraulic motors with high inertia loads, a semi close
loop circuit is constructed and its output torque could adapt the load
automatically. Energy converting efficiency is increased considerably.
Based on these, correspondent plus frequency modulated velocity control
method is put forward. Theoretical analyses and experiments show that
its energy saving effect, together with its anti-disturbance ability is
good, but its output velocity is fluctuant slightly.
Key words: High inertia loads Multiple actuators compounded control
