The working principle and controller of hybrid magnetic suspension bearing system (HMB) are studied. The structure of the digital control hardware system with the fixed point digital signal processor TMS32 0 C2 5 as well as the peripheral circuits such as A / D, D / A design. The control method adopts the PID control law of resistance to integral saturation and differential mutation, and compiles the corresponding numerical control software in assembly language. Compared with the traditional magnetic bearings, this kind of bearing can significantly reduce the power consumption and the volume of the control system, and has a broad application prospect in the aviation field. With self-developed digital control software and hardware system to achieve a hybrid magnetic bearing control. Experiments show that digital control hardware system with TMS32 0 C2 5 as the core not only meets the requirements of high speed magnetic bearing controller, but also easily implements various advanced control strategies.
