Application of hybrid electromagnetic suspension in vibration energy regeneration and active control

To improve the reliability of active electromagnetic suspension and reduce energy consumption, a hybrid electromagnetic suspension that consists of linear motor and passive damper in parallel is proposed in this paper. First, a dynamic model is established and passive energy regeneration and active control systems are built. Thereafter, energy regeneration, ride comfort, and driving safety are taken as control objects. The effect of damping values on different control objects are studied, and the best values are determined. Passive suspension is taken for comparison, and comparative simulation analysis is conducted. Finally, a bench test of 1/4 suspension is performed to verify the accuracy of the simulation results.
