DESIGN OF A CONTROLLER FOR CAR SUSPENSION SYSTEM VIA STATE SPACE APPROACH

When it come to automobile performance, people will normally think about
horse power torque and zero-to -60 acceleration. However with a good power generated
by the piston engine it is still useless if the driver cannot manage to control the car. On
the other hand, a good car performance will come together with a good suspension
controlling. The propose of car suspension system is to minimize the friction between
the tires and the road surface, to provide steering stability with good handling and
having a comfort ride.
In this project , a brief information about car suspension system and how it work
will be presented. In addition , state space approach have been chose for the method in
the derivation of the mathematical modeling in designing controller to improve the
performance of the suspension system.
Besides that, the controller design method using MATLAB software are also
presented. The simulation result will help in analyzing the characteristic of the system
and also be discussed to prove the controlling effects of the suspension system.
