Abstract In order to improve the integration degree of traditional hydraulic pneumatic elevating and banlancing machine artillery, solve centralized energy system complex pipelines all over vehicle body, combine with electro-hydrostatic actuator (EHA) technology, a double variable based on EHA technology is designed, its composition working principle are introduced, application characteristics ...

This paper presents a novel nonlinear estimator called the fuzzy finite memory (FFM) state for electro-hydraulic active suspension systems, based on techniques and impulse response. The Takagi-Sugeno model is introduced to effectively describe highly systems with actuator dynamics. Compared conventional estimator, which has an infinite structure requires whole data from initial current time, pr...

The hydrostatic actuation system based on linear actuators improves the complex piston force and long transmission path of traditional electro-hydrostatic actuator (EHA). However, new nonlinear factors in direct-driven are introduced into system, which present challenges to modeling control. To improve accuracy performance prediction, this paper analyzed working characteristics an electromagnet...

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...

This paper presents a desired compensation adaptive robust control (DCARC) of single-rod electro-hydraulic actuator Compared with the existing adaptive robust control (ARC) algorithms, the DCARC algorithm presented here has the unique feature that the adaptive model compensation part depends on the reference trajectory and parameter estimations only. This unique feature has several advantages. ...
