Research of Pump- Control Electro-Hydraulic Servo System Based on Multi-Mode Extension Control

Article Preview

Abstract:

Aiming at the contradiction between rapid response, stability and accuracy in position control of pump-control electro-hydraulic servo system, a multi-mode extension control electro-hydraulic servo system was proposed, applying extension method in system design. According to the characteristic information of the system, correlation function was established by multi-mode extension control switch. The movement process was divided into three parts according to correlative degree and controlled in each zone by Bang -Bang controller, fuzzy controller and PID controller respectively. Simulation results showed that the system had rapid response and strong robustness, and can realize high precision control.
