Active suspension systems design of a light rail vehicle using MPC with preview information disturbance

This paper presents a design of light rail vehicles (LRVs) active suspension system control using model predictive control (MPC) scheme with assumption that the preview information of oncoming disturbance is available. The aims of control design are to provide ride comfort and safety. A multibody dynamical model of the tree-car train set is considered. Numerical simulation is performed to verify the performance of the proposed controller. The simulation results show that the deflections of suspension system are in the admissible range and the vertical accelaration of all cars are brought to zero. This implies that the proposed control design provides ride comfort and safety.
