This paper presents a lateral and longitudinal coupling controller for a trajectory-tracking control system. The proposed controller can simultaneously minimize lateral tracking deviation while tracking the desired trajectory and vehicle speed. Firstly, we propose a hierarchical control structure composed of upper and lower-level controllers. In th...

In this article, we address the problem of ride height tracking control of the automotive active air suspension (AAS) system with uncertain sprung mass and external time‐varying disturbances. The proposed adaptive robust control approach guarantees that (i) the ride height converges towards, and stays within, an arbitrarily small neighborhood of th...

This paper proposes a fault diagnosis method for miniature DC motors (MDCMs) in the presence of the uncertainties caused by material and random factors of the production process. In this method, the probability models of fault multiple features are established based on the advantage criterion of the maximum overall average membership to determine t...

Aiming at the impact of the complex vibration environment generated by the integrated vibration equipment on the vibration testing equipment, this paper proposes a new method to solve the vibratory synchronization problem in the compound vibration environment. A new concept of the compound vibrating field is proposed, and a new simple vibrating sys...

Self-supervised learning methods have been proved effective in the task of real-time stereo depth estimation with the requirement of lower memory space and less computational cost. In this paper, a light-weight adaptive network (LWANet) is proposed by combining the self-supervised learning method to perform online adaptive stereo depth estimation f...

This paper addresses the problem of nonlinear height tracking control of an automobile active air suspension with the output state constraints and time-varying disturbances. The proposed control strategy guarantees that the ride height stays within a predefined range, and converges closely to an arbitrarily small neighborhood of the desired height,...

This paper addresses the tasks of height and posture motion control for an electronically-controlled active air suspension (AAS) system. A mathematical model of a vehicle body with AAS system is established to describe the dynamic characteristics and then formulated into a multi-input multi-output nonlinear system by considering parametric uncertai...

This paper addresses the problem of ride height tracking for an electronically-controlled active air suspension (AAS) system in the presence of parametric uncertainties and unmodeled dynamics. A mathematical model of a quarter vehicle with AAS system is first built on the basis of thermodynamics to describe the dynamic characteristics. Then, by emp...

This paper focuses on a ride comfort based suspension (RCS) system using an optimal stiffnessdetermination method. The proposed RCS system is composed of a variable hydraulic damper with gas chamber (VHDGC) and an air spring. In this work, the detailed structure, modeling process and parameter sensitivity of the proposed VHDGC are presented. Moreov...

... We have found several applications where depth data is used along RGB data, i.e. depth-depth adaptation, and depth-RGB-adaptation. [37] uses domain adaption to reconstruct the depth map without holes from an RGB-D input whose depth map has missing information caused by the depth sensor. [38] and [20] generate depth maps from a given stereo-image input. [39] reconstructs the depth map given only a monocular image and semantic map and [40] uses RGB-D data during training and RGB data during testing to reconstruct the depth map. ...
... Recently, many studies on suspension systems have been published. e idea of using air suspension on the vehicle has been proposed by many authors [3][4][5]. In [6], Gao et al. gave views on the air suspension system. ...
... Unlike the methods used to deal with uncertain mass presented in [19], [22], the developed mass estimation can guarantee the estimation converges to zero. Moreover, we take the inputdelay into account in the controller design, and validate its effectiveness through simulation results, while in [5], [25], the authors assumed that the delay was neglectable. In [15], constant known input delay is considered, while, in this paper, unknown time-varying input delay is considered. ...
... For the past few decades, robust control of Active Air Suspension (AAS) systems has attracted a wide research interest in the automotive industry and academia due to their promising application in improving ride comfort, road holding capacity and handling stability [1]- [6]. Numerous control methods for AAS systems have been reported in the literature, such as linear-quadratic-gaussian (LQG) control [7], H ∞ control [8], [9], backstepping [2], [5], sliding mode control (SMC) [10]- [13], sampled data control [3], [14], fuzzy based control [15]- [17], and neural network based control [6], [18]- [20]. ...
... The existing solutions in terms of vibro-isolation are still being perfected, as well as new ones being developed. In the case of vehicles, the topic of controlled dampers is essential mainly due to driving characteristics, safety and comfort of passengers [1][2][3]. Many car manufacturers have already introduced or are introducing new solutions for vehicle suspensions. ...
