Continuous Time LQR Based Position Control for an Electro-Hydraulic Actuation System

Abstract

Electro-hydraulic actuators are used a lot in the industry because they have several benefits. In this study, we concentrated on managing the load position with a proportional directional control valve and a hydraulic cylinder. First, the linear quadratic regulator(LQR) control approach is discussed for a generalized linear system. Second, a linear state space mathematical model of the electro-hydraulic actuator system was built, and the control process was applied to the proposed settings. Finally, MATLAB simulation results show that the proposed solution is better. These results are based on the LQR controller implementation and load position error analysis.
