Velocity Control of Electro Hydraulic Servo System by using a Feedback Error Learning Method



In this paper, a new control method based on FEL electro hydraulic servo control with
nonlinear flux and internal friction, has been presented. The new approach based on
controllers combined by a classic PD controller and a fuzzy controller is smart. This new
technique has a good ability to control the performance and stability. Simulations have been
carried out in Matlab environment and the results are presented below.
