A new formulation to half-car active supsension control is presented. A postion-tracking approach via emulation is proposed to selectively control the heave and pitch modes of the sprung mass by taking advantage of the natural dynamics of a particular type of actuator: the electrohydraulic actuator. The new approach consists of three main steps: first, decouple the half-car active suspension system into two sub-plants; second, design a two-dimensional (2D) system with desired pitch and heave characteristics, and decouple it into two 1D subsystems; last, utilize a position-tracking approach to make each subplant emulate its corresponding 1D desired subsystem. Simulation results demonstrate the effectiveness of this new formulation.
