Electro-hydraulic Servo Valve Systems
Hydraulic systems driven by servo valves provide highly accurate control over enormous forces. A servo valve system consists of a transducer, a servo amplifier, a servo valve, and an actuator with a connected load. It is a closed-loop system used for the precise control of the output (load) parameter, such as position, velocity, or force, in response to a command signal. The output is converted...
متن کاملVelocity Control of Electro Hydraulic Servo System by Tracking Method
This paper proposes an efficient Tracking method for velocity control of an electro-hydraulic servo system (EHSS) in the presence of flow nonlinearities and internal friction. The tracking method controller is a kind of feedback error learning structure. In the proposed method, the Feedback Error Learning (FEL) algorithm is used to control the velocity. There is no need to compute the system ja...
متن کاملSliding Mode Control with Grey Prediction for an Electro- Hydraulic Velocity Servo System
This paper presents an improved reaching law, and a sliding mode speed controller, based on the improved reaching law and grey prediction compensator, is presented for an Electro-Hydraulic Velocity Servo System. The proposed control strategy can forecast and reject the disturbances and parameter variations. This system has a fast response and a good disturbance rejection capability. The numeric...

متن کاملFeed Forward Linear Quadratic Controller Design for an Industrial Electro Hydraulic Actuator System with Servo Valve
Electro-hydraulic servo actuator (EHA) system consists of several dynamic parts which are widely used in motion control application. These dynamic parts need to be controlled to determine direction of the motion. In this research paper, system identification technique is used for system modeling and the model of the system is estimated by using parameter estimation technique. This process start...
