SYNTHESIZE ADAPTIVE CONTROLLER FOR ELECTRO-HYDRAULIC SERVO SYSTEM USING DIRECT DRIVE MOTOR

Abstract

This paper proposes to build a mathematical model of a linear electric motor
to move the slide valve inlet of an electro-hydraulic actuator. First, the analysis
describes the non-linear traction characteristics of the motor as well as the
response generated from the effect of the electromagnetic force and the elastic
force of the centering spring and then builds a model for the electro-hydraulic
servo system. The second is to build adaptive control law to synthesize the
controller for the electro-hydraulic servo system and analyze the effectiveness of
the adaptive algorithm for the system. The research results are verified, and
compared on electro-hydraulic servo models in Matlab-Simulink software and
experimented on specialized equipment.
