Summary: The key request for a vehicle suspension system is to control vibration and reduce inertia forces. This is crucial for ensuring ride comfort and driving safety. By implementing semi-active damping control, the damping process in the vehicle suspension can be adjusted to minimize acceleration experienced by the driver and passengers. A mathematical full-car model in Simulink/MATLAB was used for theoretical analysis, with simulations of various road profiles as the load. The damping coefficient of the semi-active suspension system was optimized for maximum driver comfort. The results from the full-car simulation process provide a graph of output accelerations, showing kinematic excitation from road deformities at different vehicle load positions.

Summary: This paper presents a hybrid fuzzy controller structure to improve the trade-off characteristics of ride comfort and road holding in a full vehicle active suspension system. The controller utilizes two interval type-2 fuzzy logic controllers optimized for each tire, with simulation results showing simultaneous improvement in ride index and road holding. The stability of the overall closed loop system is demonstrated through phase plane analysis.

Summary: This paper presents a model predictive control methodology for a semi-active suspension with a shift delay compensation using preview road information. The proposed algorithm shows significant improvements in ride comfort, but carries a considerable computational load. A model prediction system is further introduced to compensate for the shift time delay, utilizing a full-car dynamic model and road preview information.

Summary: This study aims to demonstrate how to compute the damping coefficient of a continuously variable damper for semi-active preview control suspensions while considering the sprung-mass jerk and the controller's performance advantage. The study found that despite reducing body acceleration, semi-active suspensions with preview control display an increase in body jerk. However, an optimal preview jerk controller can improve ride comfort without degrading road holding.

Summary: This article proposes a novel multifunction electrically interconnected suspension (MFEIS) system that can reduce vibration and harvest energy at the same time. Two H-bridge circuits are used to control the energy flow. The energy flow and control procedures of each mode are studied, and two multiobjective control strategies are proposed to balance ride comfort and energy recovery performance.

Summary: A nonlinear quarter-car model is established to examine tyre-road separation dynamics, incorporating nondimensionalisation methods to minimize parameters and generalize analysis. Frequency responses and separation time are sensitively investigated, and numerical simulations are used to identify suspension characteristics that can delay or prevent contact-free phenomenon. Comparisons with traditional models show more precise frequency responses with realistic system dynamics, and model validation is conducted in the MSCADAMS platform.

Summary: This paper proposes a semi-active vibration control strategy based on magnetorheological dampers to solve the vibration problem in mine hoisting systems. Firstly, a reasonable simplified dynamic model is established and verified using the simulation results from the virtual prototype model. Then, a fuzzy skyhook damping semi-active control scheme based on magnetorheological dampers is designed. The effectiveness of this control scheme is verified by the Adams/Simulink co-simulation technique, and the results show that the RMS, mean, and maximum values of the horizontal vibration acceleration of the container are reduced by 47.32%, 22.50%, and 35.39%, respectively. This fuzzy skyhook damping semi-active control strategy has good stability and can effectively suppress the horizontal vibrations of the mine hoisting system.
