The automatic depth control electrohydraulic system of a certain minesweeping tank is complex nonlinear system, and it is difficult for the linear model obtained by first principle method to represent the intrinsic nonlinear characteristics of such complex system. This paper proposes an approach to construct accurate model of the electrohydraulic system with RBF neural network trained by geneti...

Electrohydraulic servosystems exhibit highly nonlinear behavior to the effect that classical linear controllers, e.g., PD, usually achieve a limited performance. Load static and dynamic parameters variations are also contributing to the limitation of their position and force tracking performance. This paper presents a modelbased controller applied to a fully detailed model of an electrohydrauli...

Wear and tear are usually caused by various factors, which reduce the life span of a mechanical part. In control engineering an Electrohydraulic actuator system, wear can be system or controller itself. This article examines chattering effect that occurs during sliding mode (SMC) design, its on nonlinear electrohydraulic (EHA) system. To examine phenomenon, signum function is first applied swit...

Electrohydraulic servo system has been used in industry in a wide number of applications. Its dynamics are highly nonlinear and also have large extent of model uncertainties and external disturbances. In order to in-crease the reliability, controllability and utilizing the superior speed of response achievable from electrohydraulic systems, further research is required to develop a control soft...

There are a variety of factors affecting steering performance on off-road vehicles, including vehicle dynamics and soil stiffness. It is essential to understand the steering dynamics for designing a reasonable electrohydraulic (E/H) steering control system for wheel-type tractor. A computer-controlled E/H steering simulator, consisting of a steering actuator and a steering load simulator, is an...
