Lateral acceleration control and linear quadratic regulator (LQR) theory are used to design active roll control systems for heavy goods vehicles. The suspension consists of a limited bandwidth hydraulic actuator in series with an anti-roll bar. The procedure used to determine suitable controller gains is described. The simulation results show that roll control of a single-unit lorry requires an actuator bandwidth of 6 Hz and mean power of approximately 17 kW for a worst case random steering input. The static roll-over threshold of this vehicle is increased by 66 % when compared with the same vehicle with passive suspensions and the r.m.s. lateral load transfer is reduced by 34 % for a typical random steering input.
