Abstract
This paper proposes a novel hydraulic circuit for a single rod cylinder controlled by a variable displacement pump. The circuit arrangement not only gives the system high energy efficiency but also improves upon the internal instability of traditional circuits. Stability is illustrated by comparing traditional circuits with the proposed circuit. The motivations, derivations, and proofs of the system dynamical stabilities are presented. Control algorithms including stability control and sliding to the desired working region are presented. Experiments are conducted to verify the circuit, and results show that the circuit has good performance.Keywords
