The controllability and observability of parallel magnetic suspension systems are investigated analytically. A parallel magnetic suspension system has multiple floators and electromagnets driven by a single amplifier. In this paper, the multiplicity is set to an arbitrary counting number n . Parallel systems are classified into four types based on the output of the power amplifier and the connection of the coils. This paper treats three of them: current‐controlled with series‐connected coils; voltage‐controlled with series‐connected coils; and voltage‐controlled with parallel‐connected coils. The conditions of controllability and observability of each system are clarified. The feasibility of parallel magnetic suspension is demonstrated by simulations and experiments.
