Servo pneumatic control systems are able to generate a big forces and high speeds with a high
accuracy. Thanks to proportional valves we are able to control the accuracy and speeds of
motions in servo pneumatic circuits.
Depending on the goal, alm
ost we use the linear cylinders. And we achieved a simulation of
servo pneumatic system using a single and double solenoid proportional valve for inducting
and control. And we confirmed here, that we can choose servo pneumatic components, sizes
and specifications by working on the model translated into linear, then checking the effects of
this model comparing with the complete nonlinear system.
This will help in choosing the components of servo pneumatic systems more easily and helping
the designer to achieve more complicated actual systems with more durability and less cost and
efforts to achieve the needed results.
Hydraulic drives are able to generate high forces and move large loads. With the help of proportional
valves, it is possible to control movements fast and accurately.
Depending on the application, a linear cylinder, a rotary cylinder or a rotary mo
tor are used. Linear
cylinders are most frequently used. The following designs are therefore confined to this type of drive. We
compare among various types of cylinders which are common by used. We compared different conditions
for cylinders with friction and without it.
