Abstract-Hydraulic wind power transfer systems exhibit a highly nonlinear dynamic influenced by system actuator hysteresis and disturbances from wind speed and load torque. This paper presents a system identification approach to approximate such a nonlinear dynamic. Piecewise affine (PWA) models are obtained utilizing the averaged nonlinear models of hysteresis in a confined space. State-space representation of PWA models is obtained over the allocated operating point clusters.The experimental results demonstrate a close agreement with that of the simulated. The experimental results and simulation show more than 91% match.Index Terms-Hydraulic wind power systems, nonlinear systems, piecewise affine (PWA) models, system identification.

“…Also, to transmit the captured power, one or more fixed displacement hydraulic motors are employed. At the upstream, the implemented pump transforms the mechanical power from the blades' shaft to the pressurized fluid and then the captured energy is transferred to the hydraulic motors through hydraulic hoses and pipes [8,19]. Wind power is harvested using a high-torque low speed turbine.…”

Abstract__ Hydraulic wind power transfer systems allow collecting of energy from multiple wind turbines into one generation unit. They bring the advantage of eliminating the gearbox as a heavy and costly component. The hydraulically connected wind turbines provide variety of energy storing capabilities to mitigate the intermittent nature of wind power. This paper presents an approach to make wind power become a more reliable source on both energy and capacity by using energy storage devices, and investigates methods for wind energy electrical energy storage. The survey elaborates on three different methods named "Battery-based Energy Storage", Pumped Storage Method, and "Compressed Air Energy Storage (CAES)".

“…Fu et al [18] proposed the method for supporting agricultural priority drivers manually operated steering and designed the electrohydraulic automatic steering scheme. Wu et al [19] developed a hydrostatic transmission hardware-in-the-loop simulator for supporting vehicle transmission system research; they used linear parameter-varying approach to model the simulator and used swept-sine technique for identifying the models in the frequency domain. Similarly, Rovira-Más et al [20] investigated the dynamics of an electrohydraulic steering system and characterized the performance of an electrohydraulic valve with the aid of a set of experiments conducted on a hardware-in-the-loop electrohydraulic simulator.…”

The most of tractors employed in agriculture are equipped with an electrohydraulic actuator to implement steering control to realize automatic navigation. Electrohydraulic steering system plays an important role in realizing accurate steering control for an automatic navigation tractor because of its complicated characteristics. The objective of this paper is to develop an electrohydraulic steering control system used for automatically guided agricultural tractors. As for the identified electrohydraulic steering system model, a modified Smith control structure was discussed. Based on the structure, an improved design method for voltage servo controller and disturbance rejection controller was proposed to enhance the performance of the steering control subsystem. The effectiveness and the superiority of the proposed method were verified by simulation under Matlab. Simulation results demonstrated the efficiency of the proposed method by showing fast response, control accuracy, and robust performance for the steering control system.
