| Summary: | The main purpose of vehicle suspension system is
to isolate the vehicle main body from any road geometrical
irregularity in order to improve the passengers ride comfort and
to maintain good handling stability. The present work aim at
designing a control system for an active suspension system
which is widely applied in today’s automotive industries. The
design implementation involves construction of a state space
model for half vehicle with four degree of freedom and a
development of full state-feedback controller using Linear
Quadratic Regulator (LQR) techniques. The performance of
active suspension system was assessed by comparing its response
to that of passive suspension system. Simulation using
Matlab/Simulink environment shows that, even at resonant
frequency the active suspension system develops a good dynamic
response and a better ride comfort when compared with the
passive suspension system. |
