In this paper, a permanent magnet (PM) electro-dynamic suspension and electro-magnetic suspension (EDS & EMS) hybrid suspension system is proposed to overcome the shortcomings of the under-damped dynamics in a PM EDS system. The linearized model is established and its stability is also analyzed using the Routh criterion. According to the rational distribution between the repulsive force and the electromagnetic force, a controller is designed to meet the dynamic performance required in practical applications. A novel maglev system using a hybrid suspension scheme is also presented in this paper. Furthermore, a single-degree-of-freedom (SDOF) hybrid suspension experimental mechanism is established, and some experiments have also been undertaken to validate its effectiveness on suppressing the oscillation of the PM EDS system caused by external disturbances.
