“…To this day, many control theories have been applied to the research of the ECAS control. Chen, Hyunsup, et al [11,12] used the sliding mode variable structure control, which can effectively overcome the nonlinearities and uncertainties in the process of filling and deflating air springs. Ma et al proposed a nonlinear model predictive control method, which aims to achieve the whole-vehicle attitude control during the vehicle height adjustment control [13].…”

To address the large height error and attitude destabilization phenomenon in regulating the frame height of trucks with electronic control air suspension (ECAS), a height control strategy was designed. Firstly, the fundamental principles of height control were elucidated based on the single degree-of-freedom (DOF) vehicle model. The limitations of the classic non-linear mathematical model for the air spring were also highlighted. Thus, a dynamic model was constructed, consisting of an AEMSim model for the ECAS and a Simulink model for the truck. A frame height fuzzy controller was designed based on the fuzzy control theory to improve the height control accuracy and to solve the control conflict problem of the solenoid valves. Additionally, three typical control modes of the height and corresponding control strategies were proposed based on the practical requirements of usage scenarios for trucks. Finally, dynamic simulations were conducted under different modes. The results show that, compared to the existing switching control method, the proposed control approach can reduce height control errors by an order of magnitude and decrease the pitch angle by over 30%. The steady-state error remains nearly unchanged under the 30% variation of the sprung mass. The proposed control approach exhibits the superior control performance and robustness. It effectively reduces height errors and avoids the posture instability during the adjustment of the ECAS.

“…When the vehicle is turning at high speed, the centrifugal force will pull the vehicle to the outside of the turn, and the force is proportional to the square of the vehicle's speed. This force will cause the vehicle to tilt, and if the centrifugal force is greater than the friction force between the tires and the ground, the vehicle will roll over [4][5].…”

This article deals with the problem of controlling the stiffness of the air suspension system to help stabilize the body when the vehicle is moving around. Through the simulation of the change of the suspension stiffness parameter using Matlab simulink software, this paper has shown the impact of external force on the change of air suspension stiffness through simulation graphs. Based on the specifications of the Thaco Mobihome vehicle, simulation results have shown that there is a control to change the air suspension stiffness to help the vehicle move more stably and safely in the horizontal direction when the vehicle is moving around. From the results of this study, it has also been shown that the application of air suspension system for passenger cars will completely improve the level of stability and safety for passengers.

“…The predictive control model for the pneumatic suspension system has also been used, the effect of which is extremely positive [31]. The sliding mode control method has also been shown in the studies of Chen et al and Zhou et al [32,33]. Besides, other control methods for the active suspension system that have been highly effective can also be applied to the pneumatic suspension system [34][35][36][37][38][39].…”
