ABSTRACT
ABSTRACT: The paper studies the development of a self-powered and self-contained active lateral secondary suspension system with local sensors to implement the modal control concept for the independent control of the lateral and yaw motions for railway vehicles. The two actuators mounted on the front and rear ends of a vehicle body frame will work independently without the need for communication between them and be self-powered without any external power supply. The development of the active control algorithms for the active modal control using the local sensors are presented and the trade-off between the ride comfort improvement and energy consumption of the actuators is investigated. Simulation results are used to validate the active control design and to show that a good balance between the ride comfort and the energy balance for the two independent actuators is achieved.
