Velocity 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 کاملTheoretical and Experimental Study on Hydraulic Servo Position Control System with Generalization Pulse Code Modulation Control
In this paper, the hydraulic servo position control system with generalization pulse code modulation (GPCM) control is studied. The flow rate of the GPCM control system is controlled by a series of N solenoid on-off valves which are calibrated having different flow, and are activated by N bits binary pulse codes. In traditional PCM control, the flow rates of valves are arranged increasing accor...
متن کاملExperimental evaluation of position control methods for hydraulic systems
This paper presents a unified and systematic assessment of ten position control strategies for a hydraulic servo system with single-ended cylinder driven by a proportional directional control valve. We aim at identifying those methods that achieve better tracking, have a low sensitivity to system uncertainties, and offer a good balance between development effort and end results. A formal approa...
متن کاملSelf-tuning Position and Force Control of a Hydraulic Manipulator
Tele-operated hydraulic underwater manipulators are commonly used to perform remote underwater intervention tasks such as weld inspection or mating of connectors.Automation of these tasks to use tele-assistance requires a suitable hybrid position/forcecontrol scheme, to specify simultaneously the robot motion and contact forces. Classicallinear control does not allow for the highly ...
متن کاملHigh Precision Position Control of Electro-Hydraulic Servo System Based on Feed-Forward Compensation
The study is focused on an electro-hydraulic servo system which is a position control system. It is a non-minimum phase system when it was discretized with a certain sample time. To improve its tracking performance and extend its bandwidth, based on invariance principle, feed-forward compensation is developed by pole-zero placement theory for the system. The task is accomplished by transforming...
