The application of direct drive volume control in the bucket wheel machine control

This paper introduces a kind of hydraulic control system using direct drive mode to rotate bucket-wheel, presents the principle of the system and the difference between conventional throttle control, valve control and direct drive. The simulation model of bucket-wheel direct drive hydraulic system was established and simplified correspondingly. Eventually got the transfer function of the system. This paper analyzes the stability and rapidity of system using Matlab Simulink tools for system simulation, and shows the influence of various parameters on the system based on the structure of the transfer function and the simulation result, it has certain practical value.
