四轴液压加载试验台双泵恒压及流量协调控制稳定性研究
Stability Analysis of Constant Pressure and Flow Coordinated Control in a Dual-pump System for Four-axis Hydraulic Loading Test Benches
摘要
Abstract
An in-depth analysis of the control mechanism is conducted.A mathematical model of the system is developed using the block diagram method,followed by reasonable simplification of the block dia-gram,from which the open-loop transfer function is derived.Based on the Bode stability criterion,the sta-bility conditions for the system are established,and the key factors influencing system stability are identified and analyzed.For the developed four-axle hydraulic loading test bench utilizing this dual-pump supply sys-tem,an AMESim simulation model is built using actual system parameters.Under identical operating con-ditions,the simulation results closely match the experimental curves,validating the accuracy of the simula-tion model.Using this validated model,the proposed stability conditions are thoroughly verified.关键词
