Original Kurzfassung:
Commonly used hydraulic cylinders have piston and piston rod. Piston divides the inside of the cylinder in two chambers and pressure affecting the piston generates the
linear motion. Use of distributed valve system enables several control modes in a system of this type because different control edges can be controlled independently.
These control modes can be used for decreasing energy consumption and improving controllability. Traditional hydraulic cylinder has only a limited number of control
modes, but by utilizing a multi-chamber cylinder the number of control modes can be increased. This paper introduces a three chamber digital cylinder along with distributed
digital valve system and its controller. Characteristics of the digital cylinder are studied in a 1-DOF boom mock-up.
