A semi-active suspension system is considered to be one of the most realistic solutions for improving the ride quality of large commercial vehicles, because of its smaller energy consumption compared with that of active suspension systems. A semi-active suspension system is classified as a kind of bilinear system to which linear control theory cannot be applied. A new method of designing a controller for semi-active suspension systems using quasi-linearization and frequency shaping is proposed. The validity of the proposed method is shown by computer simulation results and vehicle test results for a sight-seeing bus.
