An Experimental Study on the Position Control of a Hydraulic Cylinder using a Fuzzy Logic Controller

Abstract

In this paper, a fuzzy-PID controller implemented in the personal computer PC/XT is proposed and applied to control the position of a servo-hydraulic cylinder. The experimental results show that the performance of the control system with variable load is excellent. This indicates that the proposed controller is one of the possible approaches to control a nonlinear and time-varying hydraulic system.
