| Summary: | This paper presents the control of the suspension system, which has a very important place in terms of road handling and passenger comfort for land vehicles. For the control system, the model consisting of a single wheel system with one-fourth mass of vehicle is used, which is known as a quarter-car model in the literature. Firstly, the mathematical models of passive and active suspension systems have been presented, and the controllers have been designed for the active suspension system. The controller designs have been obtained by optimization with linear matrix inequalities (LMI). In the study, linear quadratic regulator (LQR) control and linear quadratic integral (LQI) control have been designed, and their performances have been compared against the road disturbances. |
