In this paper, a nonlinear adaptive robust control method is presented for a single-rod electro-hydraulic actuator with unknown nonlinear parameters. Previous adaptive control methods of hydraulic systems always assume that the system's unknown parameters occur linearly, but, in a practical hydraulic system, unknown nonlinear parameters, which enter ...

Adaptive sliding mode position control of electro-hydraulic servo system with single-rod actuators
2013 IEEE International Symposium on Robotic and Sensors Environments (ROSE), 2013An adaptive sliding mode control technique is presented for an electro-hydraulic servo system with single-rod actuators in the presence of uncertain nonlinearities and unknown dynamics in this paper. The influence of different wording area of the single-rod actuator to dynamics of the system is regarded in contrast to double-rod.

This paper presents an indirect adaptive robust control (IARC) of electro-hydraulic systems driven by single-rod hydraulic actuators. Unlike the tracking-performance-oriented direct adaptive robust control (DARC) algorithm, in addition to good output tracking performance, the IARC also focuses on accurate parameter estimates for secondary purposes such

This paper studies the coordinated motion control of a hydraulic arm driven by single-rod hydraulic actuators (a scaled down version of an industrial backhoe/excavator arm). Compared to conventional robot manipulators driven by electrical motors, hydraulic arms have a richer nonlinear dynamics and strong couplings among various joints (or hydraulic ...

In hydraulic robots, single-rod electro-hydraulic actuator is widely employed for fast response, small size-to-power ratio, large output force and compact size. The differences of open loop gains and other parameters make the dynamic characteristics of two moving directions asymmetric in symmetric valve controlled asymmetric cylinder system.

Regulator and Tracking System Design for a Single-Rod Hydraulic Actuator via Pole-Placement Approach
Volume 7: Dynamic Systems and Control; Mechatronics and Intelligent Machines, Parts A and B, 2011Due to the nonlinear dynamics of hydraulic systems, applying high performance closed-loop controllers is complicated. In this paper, a single-rod hydraulic actuator is considered in which load displacement (for positioning purposes) is controlled via manipulation of the input voltage to the servo-valve. Dynamics of the servo-valve is described by first

Electrohydraulic actuators are widely used in automation industries. This paper presents a robust position controller of single-rod electrohydraulic actuators. The design methodology is based on the twisting algorithm(TA) with an integral sliding surface. The TA is one of the most promising high-order sliding-mode control algorithms.
