A Review of Active Yaw Control System for Vehicle Handling and Stability Enhancement
Muhamad Khairi Aripin,Yahaya Md Sam,Kumeresan A. Danapalasingam,Kemao Peng,N.R. Hamzah,Muhamad Fahezal Ismail +5 more
TL;DR: In this article, the vital elements for control system design of an active yaw stability control system; the vehicle dynamic models, control objectives, active chassis control, and control strategies with the focus on identifying suitable criteria for improved transient performances.
Proceedings ArticleDOI
Yaw stability improvement for four-wheel active steering vehicle using sliding mode control
TL;DR: In this article, a robust control algorithm of sliding mode control is designed for four wheel active steering (4WAS) vehicle, and simulation for 4WAS and front steering is carried out in Simulink for step steer and double lane change maneuver to verify the effectiveness of the proposed control system.
Proceedings ArticleDOI
Segmentation of brain MRI image based on clustering algorithm
TL;DR: The results demonstrate that the proposed method, known as Adaptive Fuzzy K-means (AFKM), is suitable to be used as segmentation tools for MRI brain images using image segmentation.
Proceedings ArticleDOI
A linear model of quarter car active suspension system using composite nonlinear feedback control
Muhamad Fahezal Ismail,Kemao Peng,N.R. Hamzah,Yahaya Md Sam,Muhamad Khairi Aripin,Mohd Hanif Che Hasan +5 more
TL;DR: In this paper, a composite nonlinear feedback (CNF) control technique is successfully applied to design the controller based on control law for an active suspension system and the simulation results show that CNF controller is better than LQR controller and passive model.
Proceedings ArticleDOI
Improved switching strategy of single-phase matrix converter as a direct AC-AC converter
TL;DR: In this article, an improved switching strategy sequence of single-phase matrix converter (SPMC) as a direct AC-AC converter modulated by the sinusoidal pulse width modulation (SPWM) was implemented using MATLAB/Simulink with the SimPower System Block Set.
