The principle and realisation of the hydraulic servo control with generalized pulse code modulation

摘要

This paper proposes the hydraulic servo control with generalized pulse code modulation, reseawrches the principle and realisation method of the hydraulic servo system with the generalized pulse code modulation control, builts the mathematical model of the asymmetric hydraulic cylinder servo system using this method, and analyzes dynamic and static characteristics of the system. The simulation result shows that the method can reduce contradictions between control accuracy and scope, and between stability and fast-speed characteristic.
