Multiple electrostatic suspension suspends multiple floator with a single power amplifier. The controllability of the parallel-connected double suspension system was previously analyzed, and the conditions to be controllable were shown. To test the analytical results, 1-DOF suspension systems were fabricated, and they composed a parallel-connected double electrostatic suspension system. The feasibility of double electrostatic suspension was demonstrated experimentally. This paper showed a basic model of proposed system, the controllability, and the realization of double electrostatic suspension with the fabricated suspension system. Dynamic characteristics of double electrostatic suspension was researched based on frequency responses.
