| Summary: | This paper presents a new method to design a semi�active suspension system. A semi-active suspension is
developed by installing a variable shock absorber parallel
with the passive suspension system and controlled using PID
controller. A high fidelity mathematical model for capturing
the realistic dynamic of car passive suspension system for
the basic element of the semi-active suspension system is
determined using the intelligent system identification. The
car passive suspension system is assumed to have NARX
model. The result shows that the response of the semi-active
suspension system can follow the input signal, it means the
PID controller is successfully control the variable shock
absorber in order eliminate the road surface disturbances
effect to the car body. |
