Research of the relay-linear control of an electro-hydraulic servo drive on FESTO learning system

Abstract

Abstract The task of a relay-linear control algorithm for an electro-hydraulic servo drive (EHSD) was considered. This algorithm provides reconfiguration of the state components feedback coefficients at the very initial stage of the control object movement, when the optimized control action does not depend on these coefficients. A FESTO hydraulic learning system combined with Matlab+Simulink Desktop Real Time was used for realization of the developed algorithm. Experimental results are included.
