Extension Control Research of Pump-Control Electro-Hydraulic Servo System

Abstract:

The extension control is a newly developed intelligent control method used to solve control problem from information transformation presented based on extenics. Firstly some basic concepts about extension control were introduced, on this basis, the extension control algorithm was improved and the extension control was applied to pump-control electro-hydraulic servo system. The simulation and experimental results show that the pump-control electro-hydraulic servo system based on extension control has such advantages as quick and stable response, simple parameters determination and excellent dynamic quality, with a better prospect for development.
