An active magnetic bearing digital controller is presented. This system is based on high-speed floating-point digital signal processor (DSP) and field programmable gate array (FPGA). The active vibration control algorithms are coded in C language where is possible to reduce the probabilities of software errors occurring and to reduce the debugging time for those errors and are executed by the high-speed floating-point DSP. This paper describes the implementation of the controller. The proposed digital control system can meet the requirement of enough throughput which is difficult using a single fixed-pointing DSP, realize integration of magnetic bearings controller and have the merits of easily to maintain and be applied in other magnetic bearings systems. The system has been applied successfully in several actual magnetic bearings systems at Beijing University of Aeronautics and Astronautics and the experimental results verify its feasibility.
