Synchronization Control and Electromechanical Coupling Characteristics of Pile Hammer Synchronous Vibration System

Abstract:

Control technique is an effective way to synchronize multi vibration hammer. For the problem of electromechanical coupling in the control of two vibration hammers, the dynamics equations of the vibrating system and mathematical model of electromechanical coupling were established. Then the simulation model of Matlab/Simulink was established, and the simulation results show that the self synchronous occurs only under certain conditions during electromechanical coupling. Synchronous control strategies and algorithms were studied in the condition of electromechanical coupling, a synchronization control mode named “virtual master + PID” was established. In the end, experiments verify the characteristics of electromechanical coupling and the synchronous control strategies as well as the algorithms, and the synchronization accuracy proves to be able to meet engineering application.
