Experimental Verification of Discrete Linear-Quadratic-Gaussian Control System of Electro-Hydraulic Servodrive

This paper presents the design of a discrete Linear-Quadratic-Gaussian (LQG) controller for the electro-hydraulic servodrive position control. The controller is based on the identified linear model of the system. There are given experimental results of the proposed control system and a comparison with a control system with Proportional-Derivative (PD) controller.
