Understanding the Dynamic Characteristics of a Regulated Loading System

Abstract

Loading system is the most important system of multi-functional engineering machinery. This paper analyzed the mathematical models of electro-hydraulic servo valve and variable fuel tanks. By using the PID controller to adjust the parameters, mainly from step loading model and sine wave loading model to analysis the simulation. Studying on dynamic characteristics and reliability of the secondary regulation technology system for loading control system of test-platform. The results show that the construction machinery multi-function test-platform uses the secondary regulation technology system is feasible, the secondary regulation technology can meet the performance requirements of the loading system.
