Using Fuzzy Logic to Control an Innovative Active Vehicle Suspension System

Popis výsledku v původním jazyce

In this paper, a basic way to fuzzy logic unit utilization on vibration isolation device driver development is briefly described. In this paper, fuzzy logic is used to simulate active suspension of vibrations by linear electric motor on a one-quarter and one-half-car models. Fuzzy approach is one of the frequently used active research and development areas at the present time, particularly in the automobile industry because fuzzy logic can improve vehicle ride comfort and road handling performance. The ride comfort is improved by means of reduction of the body acceleration caused by the car body when road disturbances from uneven road surfaces, pavement points, cargo mass changes, etc. act on the tires of running cars. Velocity and acceleration of the front and rear wheels and undercarriage velocity above the wheels are taken as input data of the fuzzy logic controller. Active forces improving vehicle driving, ride comfort and handling properties are considered to be the controller outputs. The controller design is proposed to minimize chassis and wheels deflection when disturbances are acting on tires of running cars. As a result, a comparison of an active suspension fuzzy control and a spring/damper passive suspension is shown using MATLAB simulations.
