A Study, Modeling and Smart Control Of Quarter Car Suspension System

The process of (modeling, simulation and control of linear quarter car active suspension system) is the proposed model in which the coil spring was replaced by air spring of the type of Nishimura and hydraulic damper with the use of air actuator getting to the final mathematical equalization which represent such model, aiming firstly to obtain (smart suspension system) the purpose behind is to have a better response for that systemization to active the best (handling, rid comfort and stability). The car through using such systemization and compare the response with the normal suspension systemization which are used in coil spring hydraulic damper and actuator whereas it is depended on the Displacement of the car body resulted from car effectiveness of the road circumstances as a standard in the process of outline the results from this paper with applying the rules of fuzzy controller that can be shown in item (IV).
