摘要

摘要为改善磁流变悬架系统的减振效果，对某自研磁流变减振器阻尼力可控特性及其时频响应特性进行了台架试验，结合灰色预测理论与传统模糊控制，提出灰预测模糊控制策略并应用于磁流变悬架控制系统。为验证该方法的有效性，分别对天棚控制、传统模糊控制及灰预测模糊控制进行了仿真与试验对比研究。结果表明该磁流变减振器阻尼力可控效果显著且响应快、频带宽；仿真和试验均显示灰预测模糊控制对幅值的抑制效果较好，响应时间优于传统模糊控制但不及天棚控制。

Abstract

Abstract: For purpose of improving the vibration absorption effect of magneto-rheological (MR) suspension sysytem, the bench test of response characteristic both in time and frequency domain have been done for the special magneto-rheological (MR) damper. Then a grey predictive-fuzzy controller（GPFC）is proposed by integrating the grey predictive theory and the traditional fuzzy control(TFC) algorithm and is applied to the control system of MR suspension . Inorder to verify the effectiveness of the proposed control strategy, the comparative study of simultion and bentch test among sky-hook control, TFC and GPFC has been presented. The results show that the response speed of MR damper is fast, the bend of frequency response is wide. Both the simulation and test results present that the performance of the GPFC is the best, the time response is superior to that of TFC, but slower than that of sky-hook control
