This article deals with the design of a partial preview active suspension control algorithm for the improvement of vehicle ride comfort. Generally, while preview-controlled active suspension systems have even greater potential than feedback-controlled systems, their main challenge is obtaining preview information of the road profile ahead. A critical drawback of the “look-ahead” sensors is an increased risk of incorrect detection influenced by water, snow, and other soft obstacles on the road. In this work, a feasible wheelbase preview suspension control algorithm without information about the road elevation has been developed based on a novel 3-degree-of-freedom full-car dynamic model which incorporates only the vehicle body dynamics. The main advantage of the employed vehicle model is that the system disturbance input vector consists of vertical wheel accelerations that can be measured easily. The measured acceleration information of the front wheels is used for predictive control of the rear suspension to stabilize the body motion. The suspension state estimator has also been designed to completely remove the effect of unknown road disturbance on the state estimation error. The estimation performance of an observer is verified via a simulation study and field tests. The performance of the proposed suspension controller is evaluated on a frequency domain and time domain via a simulation study. It is shown that the vehicle ride comfort can be improved more by the proposed wheelbase preview control approach than by the feedback approach.

“…In recent years, the application of H ∞ control method has achieved a lot of research achievements in the multi-objective control of active vehicle suspension. 2–7 These H ∞ control methods could not only improve the ride comfort, but also guarantee relevant time-domain hard constraints. Due to the strong robustness of the method, many scholars have studied the H ∞ control method that considers actuator faults and time-delay.…”

In this article, a novel sliding mode tracking control scheme for vehicle active suspension systems with matched and mismatched uncertainties is proposed based on super-twisting concept. In order to stabilize suspension deflection motion to the desired trajectory in finite time, a finite-time sliding mode controller is designed. Specifically, a novel trajectory function is proposed to adjust the suspension performances (e.g. ride comfort, tire dynamic load and suspension deflection). Compared with the first-order sliding mode control method, the proposed tracking control scheme can effectively improve the ride comfort and ensure the suspension deflection constraint. The control scheme requires only the suspension deflection and acceleration feedback and thus is easy to implement. The uncertainties of the active suspension system are considered as a total disturbance term which can be estimated online, and the estimated error can become a vanishing term in finite time using an extended super-twisting disturbance observer. Finally, the proposed control algorithm is applied to a quarter-car active suspension model, and numerical and experimental results are provided to show the merits and effectiveness of the proposed control scheme.
