Assessment of the Magnetic Hysteretic Behaviour of MR Dampers through Sensorless Measurements

Shock and Vibration, 2018
Magnetorheological (MR) dampers are well-known devices based on smart fluids. The dampers exhibit nonlinear hysteretic behaviour which affects their performance in control systems. Hence, an effective control scheme must include a hysteresis compensator.

The Evolution of Vehicle Pneumatic Vibration Isolation: A Systematic Review

Shock and Vibration, Volume 2023, Issue 1, 2023., 2023
Whole‐body vibration (WBV) is a significant concern for vehicle users as it can negatively impact their health and comfort. As such, effective vibration isolation is critical in vehicle suspension design. The ability of a vehicle suspension to isolate vibrations depends primarily on the suspension design and the type of springs used. One type of spring

Modeling and Design of ANFIS Dynamic Sliding Mode Controller for a Knee Orthosis of Hemiplegia

Applied Bionics and Biomechanics, Volume 2023, Issue 1, 2023., 2023
The use of assistive devices to control the loss of strength and range of motion of hemiplegic patients is becoming common. It is difficult to develop a precise control approach for a knee orthosis system because of the unpredictability of the dynamics and the unwanted subject’s spasm, jerk, and vibration during gait assistance.
