An electronic control scheme is presented for improving suspension performance in heave and pitch control as compared with simple passive suspensions. In general, the heave and pitch motions are coupled and an impulse at the front or rear wheels excites both motions. This means that pitch controllers and heave controllers cannot be independently designed. Therefore, the model includes the full vehicle suspension dynamics considering both heave and pitch motions. The controller design is based on time-scale separation and an ininput decoupling transformation that allows streamlined design yet gives performance better than over-simplified decoupled techniques.
