Abstract
This paper offers with the theoretical and computational evaluation
of optimal & robust control problems,
with the goal of providing answers to them with MATLAB simulation.
For the robust control, -synthesis controller
and for the optimal control, LQR controller are designed for a quarter
car active suspension system to maximize the
ride comfort and road handling criteria’s of the vehicle. The proposed
controllers are designed using Matlab script
program using time domain analysis for the four road disturbances
(bump, random sine pavement and white noise)
for the control targets suspension deflection, body acceleration and
body travel. Finally the simulation result prove
the effectiveness of the active suspension system with Mu-synthesis
controller.
