Valve controllability is an important criterion in hydraulic linear actuators due to its direct influence on system performance. In contrast to the spool controlled valve, the magnetorheological fluidMagnetorheological fluid valve utilizes the special characteristics of the fluid to improve the controllability. However, the dynamic model is compulsory for better understanding of the magnetorheological fluidMagnetorheological fluid (MR) valve response. This paper aims to develop a dynamic model for a single MR fluid valve. Because of the complexity in interaction between the magnetic field and the iron particle in the MR fluid, a CFDComputational Fluid Dynamics (CFD) approach was used in this study to model the fluid flow in the valve. CFDComputational Fluid Dynamics (CFD) data was then used as an input in the NNARXNNARX structure for dynamic modeling of the valve. The hybrid CFD-NNARXNNARX model for the MR fluid valve shows a good agreement with the experimentExperiment with 4% error. The model was also applied in the controller design and reduces the settling time up to 20%. These models significantly reduce the difficulty in designing the linear actuator controller.
