A Non-linear Energy Sink (NES) controller is designed and used to control actively or semi-actively the dynamics of vehicle suspension systems. A vertical vehicle dynamic model is developed to demonstrate the effectiveness of the NES controller. The proposed controller utilises non-linear spring and damping elements, which are attached to the primary suspension system. The non-linear damping elements reduce the dynamic load of the tyres and improve the handling performance, while the non-linear spring elements absorb vibration energy transmitted by road disturbance and improve the vehicle ride comfort. Simulation results show that the proposed controller can potentially achieve a balance between ride comfort and handling performance.
