考虑参数不确定性的主动悬架预瞄自抗扰前馈补偿控制
Preview active disturbance rejection feedforward compensation control of active suspension considering parameter uncertainty
摘要
Abstract
The preview control effect of the automobile active suspension system is easily affected by factors such as vehicle speed,suspension parameter uncertainty,and road information perception accuracy.To address the issue,an active suspension preview control method based on an improved Active Disturbance Rejection Control(ADRC)algorithm is proposed.This method thoroughly considers the uncertainty of sprung mass,stiffness,and damping in the suspension system,builds a vehicle suspension model with uncertainty,improves the gain function in the ADRC algorithm,and designs an active suspension preview control system with feedforward compensation.Then,the influence of external disturbances such as measurement noise and signal processing interference on the control effect of the proposed method is simulated and analyzed on random road and pulse excitation road.Finally,a hardware-in-the-loop test system is built to validate the performance of the control system in conditions close to actual deployment.Results show the proposed method effectively improves the vehicle body vibration over a wide speed range under system state changes and disturbances,exhibiting fairly good robustness.关键词
