Adaptive Event-Triggered Active Suspension Control with Rollover Prevention
摘要
This paper introduces a vehicle active suspension control system that integrates anti-rollover control strategy and event-triggered mechanisms. The primary aim of the anti-rollover strategy is to enhance vehicle roll stability by managing the roll angle and rollover index, particularly under conditions involving bump road surface and large steering angle. While realizing the essential function of the suspension system in mitigating road-induced vibrations, the proposed approach can also minimize the risk of rollover. The designed event-triggered H∞ controller can effectively achieve the control objectives, and the control input is constrained. At the same time, benefit by the application of event-triggering mechanism, the designed controller can effectively save the communication resources of the in-vehicle network. Finally, simulation results, obtained by using MATLAB/Simulink, demonstrate the effectiveness of the proposed active suspension control system in isolating vibration and preventing rollover under different disturbance input across two test cases.
