Tracking control of an electro-hydraulic actuator system using LQR-ZPETC controller. ELEKTRIKA- Journal of Electrical Engineering, 20 (2). pp. 8-13. ISSN 0128-4428 (2021)
Abstract
Electro-Hydraulic actuator (EHA) is a one type of application used in industry and building high performance of motion control process. Apparently, dealing with EHA behaviour is quite difficult and makes the controlling process complicated. Designing Linear Quadratic Regulator (LQR)controller as a feedback controller requires in selecting the weighting parameter Q and R. The result shows that the higher value of Q offers fast response and high stability by referring to the placement of closed-loop poles. However, the higher value of Q gives a higher error that can make the position performance of hydraulic actuator become worst. To overcome this problem, the feed forward controller is developed by implementing the zero-phase error track in control (ZPETC). Simulation results showed that the LQR-ZPETC method was capable to produce satisfactory tracking performance.
