Traditional Single Input Single Output (SISO) models fail to capture the complex interactions and nonlinearities inherent in vehicle dynamics, leading to suboptimal performance. The proposed method addresses these limitations by utilizing a Multiple Input Multiple Output (MIMO) framework, which accurately models the nonlinear interactions between AFS and DYC systems. Additionally, the method introduces a dynamic coefficient in the sliding mode control, enabling real-time adaptation to unknown uncertainties and enhancing robustness. The slip angle is estimated by an observer and a first-order delay is introduced into the lateral forces modeling to improve the accuracy of vehicle dynamics representation. The stability of the closed-loop system is further validated using the Lyapunov method. The performance of the proposed controller is evaluated considering the coefficient of road tire friction and parametric uncertainties in vehicle parameters, such as total mass, moment of inertia, and tire stiffness. The efficacy of this method has been rigorously confirmed through MATLAB simulations using a nonlinear 8-DOF vehicle model, which includes parameter uncertainties to ensure the control strategy's resilience to varying road conditions. The simulation results demonstrate significant improvements in the vehicle's stability and handling performance across a variety of driving maneuvers.</p>","PeriodicalId":55453,"journal":{"name":"Asian Journal of Control","volume":"27 3","pages":"1442-1454"},"PeriodicalIF":2.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim is to establish significant switching laws which allow us to obtain the individual switching duration sequence for each cycle such that the integrator switched system is practically stable. We develop a new decomposition expression of the switching duration sequences, and show that a switching duration sequence can be divided into two parts: one part contributes to the change of state during the cycle and another one is about the nonnegativity of the duration sequence. Based on the decomposition expression, a sufficient condition for the existence of the switching duration sequences are induced. We propose a switching law which ensures the practical stability of the nominal integrator switched systems with the constant period time.

In this paper, the congestion problem of EV charging is investigated within the framework of network congestion games. It takes into account congestion during both travelling and charging stages. Initially, for the scenario where no player fails, the EV charging problem is modeled as a network congestion game, which is proven to be a potential game. Secondly, two types of games with player failures are considered. The game with player failures on roads is verified a weighted potential game, drawing support from the semi-tensor product (STP) of matrices. The game in which players only fail at charging stations, rather than on roads, is not a (weighted) potential game but admits at least one Nash equilibrium (NE). Thirdly, the effect of player failures on NEs is discussed, and the condition that keeps the NE of the original game unchanged is provided.
