Electrohydraulic Servomechanisms Adaptive Control
Author: Neuhauser Jaroslav
Electrohydraulic servomechanisms adaptive control will be proposed in this paper. Electrohydraulic testing machines will be briefly introduced and their industrial applications will be discussed. We will present recursive system parameters identification, time-variant parameters tracking and adaptive control algorithm in this paper.
The goal of this work was to verify testing machines control improvement if the adaptive control theory would be used instead of PID controllers. Today's PID controllers are unsufficient, because system dynamics is varying with testing specimens changes. Within this work we have verified features of adaptive control algorithm applied to general purpose electrohydraulic testing machine. Known problems with practical use of adaptive approach will be also discussed.
