Research on RBF-PID Control for the 6-DOF Motion Base in Construction Tele-robot System

Abstract

In this paper, according to the real experiment device, we deduced the model of the electro-hydraulic servo valve and the dissymmetric hydraulic cylinder, a new RBF-PID controller was developed based on it to form a closed-loop system for the 6-DOF motion base in a tele-robotic system. To verify the validity of the design, a simulation is done. The simulation results show that RBF neural network is effective for electro hydraulic servo control systems. To control the 6-DOF realistic motions according to the signals of six acceleration sensors on the construction tele-robot, an experiment is also done. The validity of the control system was confirmed by experiment result. The control system performs steadily. And the experimental result indicates that the RBF neural network can enhances the robust control, which has reality significance.
