Abstract:
In last years, many researches are focoused on improving of suspension systems because of their importance in automotive afavourable performance. One of these advanced suspension systems are Magnetorheological suspension with nonlinear dynamic system and complicated behavior like Hysteresis Loops, so their modeling are notable.
In the first chapter as introduction, suspension systems and their aims are expressed briefly. Then Magnetorheological suspension structure and its function are mentioned. After review of researches that has done about its modeling and control , in the third chapter, different types of classic and generalized Prandtl-Ishlinskii models are introduced and magnetorheological Fluid properties are studied in brief.
The proposed model of Prandtl-Ishlinskii is presented and validated in forth chapter. In the fifth chapter Prandtl-Ishlinskii inverse model and method of obtaining that is quoted. Analysis of system error in Compensator is studied in sixth chapter and a controller is poroposed in seventh chapter.
At the end, conclusions and recommendations for further work are presented
