Abstract
Electro-hydraulic servo passive force loading system is a typical position disturbance force control system. Due to the strong external disturbances in the loading system, large number of extra force will appear. The introduction of extra force will seriously affect the system's force tracking accuracy and control effect. The Electro-hydraulic servo passive force loading system has the characteristics of time-varying, nonlinear and strong external disturbances. In order to compensate and eliminate the external disturbances effectively, this paper adopts ADRC technology to control it. The electro-hydraulic servo system is token as the research object. The generation of extra force, the composition and working principle of ADRC controller, parameter tuning rules are analyzed in detail. Finally compares the PID control method with ADRC control method through experiment, confirming that the ADRC algorithms superiority in the passive force load electro-hydraulic servo system.
