This paper is concerned with a control
design of an electro-hydraulic suspension system. In some practical problems,
for instance in the active suspension design, the state derivative signals such
as acceleration and velocity are easier to obtain rather than the state
variables such as displacement and velocity, since the most commonly used
sensors are the accelerometers. Hence, design of an optimal state derivative
feedback controller is proposed by employing the linear matrix inequalities
framework. In order to demonstrate the effectiveness of the proposed
controller, a two-degree-of-freedom quarter vehicle suspension model equipped
with an electro hydraulic actuator is preferred. Throughout the numerical
simulation studies, bump type road irregularities at different vehicle forward
velocities are applied to evaluate the performances of the controller in terms
of ride comfort and safety.
