• Control system design is discussed for a semi-active suspension system of vehicles. For the disturbance rejection problem, l_1 state feedback controllers are designed. An l_1 controller can specify the maximum magnitude of outputs against certain road disturbances in the time domain, regardless of the frequency of the road disturbances. That property enables a semi-active suspension to be formulated as an unconstrained linear system, while it is usually modeled as a bilinear system or a linear system with a constraint. In this paper, not only a controller for a nominal model, but also a controller considering robust performance is designed. Static nonlinear first order homogeneous state feedback controllers, which require a moderate amount of calculation, are constructed for the linear system by applying l_1 near-optimal control theory with an appropriate approximation method.
