“…The controller determines the amount of force required to reduce the effect of the force experienced during an impact (Nordin et al, 2018). The results indicated that implementing the F-PID controller (PID with fuzzy) in the system provides better performance in reducing vibrations than the PID controller (Nordin et al, 2018(Nordin et al, , 2022. Due to the limitations of PID, in most MRF applications, PID control strategies are combined with other control schemes (Choi et al, 2016).…”

Magnetorheological fluids (MRF) are intelligent materials that can vary their yield stress in response to an applied magnetic field. This characteristic, combined with active and multifunctional control, allows the development of actuators with fast response time, low energy consumption, long service life, and reduced dimensions and weights. Various studies have been conducted to improve MR dampers in prosthetic applications, including knees, ankle-foot, hands, and sockets. Here, we present a critical review of the progress of MRFs in the prosthetic field. In addition, research in prostheses’ design, optimization, and control of magnetorheological actuators is investigated, along with MRF modeling, mode of operation, type of MR actuator, classification, and working principle of MRF-based devices. Although MRFs are considered promising materials for designing novel prosthetic devices, this review shows that applications have been predominantly focused on lower limb prostheses. We conclude by discussing possible future applications and challenges that must be faced to enable and improve commercial applications based on MRF technology.

“…The distinctive characteristics of MR fluids have found application in various devices, where the absence of moving parts is an important advantage (Eshgarf et al, 2022; Zhu et al, 2012). Some examples include light-weight, semi-active damping devices for miscellaneous applications (Jiang et al, 2022), damping systems for ground vehicles with high dynamic range and low stroking load (Bai et al, 2013), or even MR dampers used in prosthetic limbs (Nordin et al, 2022).…”

Magnetorheological (MR) valves attracted the interest of researchers across diverse fields, owing to the controllable nature of MR fluid. The use of MR fluid in valves enables fast response, energy efficiency, and robustness, while several studies designed MR valves that can sustain high-pressure. However, although these studies present efficient solutions, they are still unable to exist in miniaturized form while maintaining high-pressure-sustaining capabilities. This paper presents the analytical, numerical, and experimental analysis of a novel miniaturized cylindrical magnetorheological (MR) valve with high performance in terms of the maximum fluid pressure it is able to sustain. The study considers the flux fringing phenomenon that enhances the value of sustained pressure. The fabricated valve is validated experimentally in closed and open states, as well as during state switching. Finally, comparisons between the analytical, numerical, and experimental results are reported. The novel MR valve demonstrates a capacity to withstand at least 1 MPa of pressure with a volume of 353 mm3 and 3.2 g weight, unlike previous studies that report these values of pressure with valves of larger size and higher structure complexity. These results hold promise for applications demanding high pressure control in constrained spaces, such as medical ones or soft robotics.

For towering structures under complex time-varying excitation, the tuned magnetic fluid rolling-ball dampers (TMFRBD) cannot achieve self-tuning damping. In this paper, considering the operating characteristics of the TMFRBD, a damper self-tuning control algorithm, namely particle swarm optimization (PSO)-FUZZY-PID, is proposed for real-time adjustment of the intrinsic frequency of TMFRBD, which can greatly improve the damping effect, namely self-tuning magnetic fluid rolling-ball dampers (STMFRBD). Firstly, the equivalent dynamics model of the damping system is established, deriving the structural dynamic amplitude response as a function of the excitation frequency to structural frequency ratio. Different frequency tracking schemes of the damper are compared and analyzed. Then magnetic field simulations and magnetic fluid magnetic property measurements are performed for the dampers, respectively. Secondly, the self-tuning PSO-FUZZY-PID control algorithm is designed to improve the damping performance of STMFRBD under time-varying excitation by optimizing factors of the FUZZY-PID controller with PSO. To confirm the effectiveness of the damper self-tuning control algorithm, the frequency tracking of dampers with different control algorithms under time-varying excitation is compared. The results show that the damper’s frequency can be tuned quickly and accurately tracking excitation frequency by PSO-FUZZY-PID. Finally, the simulation and experimental results of STMFRBD and passive mass damper (PMD) under different loads are analyzed, and the structural amplitude response is analyzed using the Hilbert-Huang transform (HHT). In addition, the damping of STMFBD and TMFBD under different loads is compared. The results show that STMFRBD has better vibration-damping performance than PMD and TMFRBD.
