A vehicle model is developed that captures the dynamics of a semi-active tri-axle air-suspension system with load sharing between three axles. Linear control systems are designed for both ‘modified skyhook damping’ (MSD) and optimal full-state feedback (FSF) control. Non-linearities in the damping elements are modelled. The performance improvements of the control strategies are quantified by measuring the percentage reduction in dynamic body acceleration (BA) and dynamic tyre force (TF) compared to the optimal passive damping case. It is found that the FSF control offers the best theoretical performance when used with the non-linear damping element, achieving reductions relative to the optimum passive case of 38% in RMS BA and 20% in RMS dynamic TF. This optimum is found only when a gain amplification factor is added into the control loop.
