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
