　　A novel two-degree-of-freedom(2-DOF)PID control scheme for a magnetic levitation system was proposed in this paper.To make the set-point tracking performance and the disturbance rejection characteristics of the system can be entirely decoupled,a new structure of 2-DOF control was designed.The reference model of the system was introduced to improve the set-point tracking performance.Then,a PID controller based on the direct synthesis approach and desired disturbance rejection characteristics is designed to improve control performance.Compared with the conventional 2-DOF PID control,this approach could reduce the number of adjustable parameters and achieve better disturbance rejection characteristics.Both simulation and experimental results show the excellent target tracking performance and disturbance rejection characteristics of the designed control system.
