HYDRAULIC DRIVE CONTROL SYSTEM WITH A STATIC NONLINEARITY COMPENSATION
Read the full article
Abstract
A relay-proportional control law supplemented with a static nonlinearity compensation of an electric hydraulic amplifier is proposed to control a position of a hydraulic drive for a linear reference signal tracking. The closedloop stability for suggested control law is shown. Experimental results are carried out on a laboratory prototype of a forestry crane and show high achieved tracking performance.
