If intermediate positions are possible, can there be a continuous range? What type of control systems do you need?
Any advice about this would be much appreciated. Any links that would be helpful?

Pneumatic cylinders are not practical to use intermediate positions but you can gang two or more together and on the same element to get one or more intermediate positions. I believe there may be two position cylinders in the Bimba line up but in either case you need two control valves to have two positions. The advantage of pneumatics is they are very fast, have lots of power and very reliable.
