Looks to me like someone wants us to do his/her homework for them.

Thank you

The question is a bit unclear. I will try to answer exactly the question:

A cylinder actuation is performed by an external force (or internal in the case of combustion cylinders). That force might be coming from a motor, steam, air under pressure, liquid under pressure, human force (you, probably, never started a car with a cranking rod) etc.

A device that controls a cylinder actuation would control all those forces.

I'm not sure I've ever heard of any cylinder being "actuated." Can you give an example?

Is there a reason your question showed up in this forum and not the General forum?

First, let's begin with terminology. I presume by use of the word "cylinder" you are referring to a pneumatic or hydraulic actuator. "Cylinder" is a slang word used to describe these devices and one that I prefer not to use. I also presume this actuator is part of a machine and it has more or less an electrically-controlled input. Your question is quite ambiguous and general so my answer is quite general.

Typically, such an actuator is connected to an energy supply source, be it fluid or air. The flow of energy available to the extension side or retraction side is determined/switched by an electric solenoid valve that is placed between the actuator and the energy supply. The electric solenoid valves fall into two (2) basic groups; normally-closed or normally-open. There are also proportioning solenoid valves in sophisticated arrangements, but let's keep it simple here.

The activation/operation of the solenoid valve is controlled by an input from a different energy source that may be switched by a PLC, limit switch, or an operator's pushbutton. Of course in the case where an actuator is manually controlled, there may be but a simple hand-operated valve.

So, the control of an actuator can be very simple (hand-operated valve) or be an extension of a machine's electrical control circuits. This is the best that I can do with this question.

Regards,

Ing. Robert Forbus

Lets just say that between the cylinder and power source is a "Connecting rod"

Sounds good to me, next question.
