In this paper, a prototype of a dual-axis magnetically levitated positioning platform is proposed and implemented. It is a repulsive maglev system consisting of two single-axis positioning sub-systems. First of all, the model of the overall system with complete DOFs (degree-of-freedoms) is derived and analyzed thoroughly. Next, an adaptive sliding mode controller which deals with the unknown parameters is well designed to regulate the 12 DOFs in this system. From experimental results, the high performance in terms of stiffness and resolution has been demonstrated, which quite matches the theoretical performance.
