“…Implementation of control strategy on MREs devices are also less reported. Analog control namely proportional, integral and derivative (PID) utilized in semi-active impact control by Fu et al [227,228] Feedforward control as most early used in MR damper semi-active control has been used by Li et al [105] Lately, nonlinear and intelligent control system have also implemented in controlling MREs devices for example control; [94] Lyapunov control [245] and Human Simulated Intelligent control. On-off control strategy has also implemented in seismic system by Collette et al [250] to adjust the natural frequency of structural building; while, Liao et al [186] tried on-off control for vehicle seat vibration.…”

Magnetorheological (MR) materials are classified as smart materials due to their responsiveness to external magnetic stimuli. Intensive research on MR materials has led to broad applications in several potential fields. A solid carrier matrix state called MR elastomer with its exceptional magnetic responsive feature is obtained by merging magnetizable particles within an elastomeric polymer. This integration results in outstanding characteristics on the rheological performances. Special prominence is given to the understanding of the base materials and fabrication as well as the functional behavior through various characterization methods. Broad applications of MREs are also explored to provide a profound market picture and to motivate researchers to develop novel technology.

This paper presents control characteristic of an impact isolator featuring a magneto-rheological elastomer isolator device (MREID). The developed MREID is analysed in term of its magnetic intensity to produce a large of MR effect that controlled by the input current. In order to control the input current, the hybrid skyhook active force control (HySAFC) is proposed. The HySAFC is used to track the signal based on the force obtained from the feedback of the force sensor and accelerometer. However, the control output of the HySAFC is desired force of the current generator which is designed using the inverse adaptive neuro-fuzzy inference system (ANFIS). Then, the selection of the input current using the IF-THEN rules depend on desired force and impact energy for current generator. Next, for the development of control structure, the impact isolation system is formulated and the impact isolation test rig is used to perform the experimental validation process. The validation assessment of HySAFC is experimentally realized, and the control responses, namely such as jerk, accelerations and transmitted forces as well as the impact isolation system are presented in the time domain. Finding of this study, the HySAFC is able to improve the MREID performance for impact loading application in simulation and experiment and capable in providing fast response when impact occurred.

“…However, limited by requiring an accurate mathematic model of MRE isolation system, the mentioned controllers are not very satisfied in control application. There are other controllers, which are independent on system model, such as ON-OFF controller [15][16][17], PID controller [18] and fuzzy controller (FC) [4,10,19] are used to mitigate the vibration of MRE isolation system. With the advantages of simple structure and easy implement, ON-OFF control is used in most MRE isolation control systems.…”

Protecting high-tech facilities from micro-vibrations in the working environment has demanded intensive research in recent years. One of the most promising devices proposed for facilities protection is the magnetorheological elastomer (MRE) isolator. To explore fully their potentials in the real-time control implementations, control strategy plays an important role. This paper proposes a nonlinear self-tuning fuzzy controller (STFC) for a MRE micro-vibration isolation system exposed to time-varying (variable frequency and amplitude) sinusoidal excitations. The silicone rubber matrix MRE isolator with low initial modulus is employed to suppress the timevarying vibration at low frequency, the performance of the proposed isolator is evaluated by sweep frequency experiments. Different from the conventional fuzzy controller (FC) with fixed parameters, which is only effective for the vibration with a certain frequency and amplitude, a STFC composed of semi-active FC and self-tuning law can suppress time-varying vibration with the wide frequency and amplitude range. In order to achieve the adaptability of the proposed controller to time-varying excitation in real time control, the nonlinear self-tuning law is designed by using genetic algorithm to optimize scaling factors. Both numerical simulations and experiments are conducted to verify the effectiveness of the designed controller. Meanwhile, the control effects between STFC and conventional FC are compared in acceleration attenuation to demonstrate the superiority of the proposed STFC. The results show that the designed nonlinear STFC is more effective for suppressing the time-varying vibration with the amplitude of 0.5-3 m s −2 and frequency of 45-60 Hz.
