Abstract  We applied modelbased design method to hybrid magnetic suspension system combing with Matlab/Simulink simulation of floatingpoint PID control and fixedpoint controller DSP2812.Based on the method and architecture， we established the control system quickly， the system model/design/simulation， as well as hardware implementation can be seamlessly integrated. Firstly， we built system model and control design for hybrid magnetic suspension system in matlab/simulink environment， and processed it by using its own fixedpoint processing on the digital controller. Simulink code model was transforred  with a digital averaging filter. Secondly， we done Oncircuit debugging and verification of the algorithm via RTDX functions，and then obtained the optimization code model. Finally， downloaded the automatically generated C code into the DSP platform for controlling the hybrid magnetic suspension system. The real experiment system was developed and the control result showed that the modelbased method can integrate and unify from model design and simulation to system implementation．

基于模型设计方法的混合磁悬浮平台的控制设计及实现

基于模型的设计方法，利用Matlab/Simulink对磁悬浮系统进行浮点数字PID控制仿真,并结合定点控制器DSP2812，实现系统控制的快速构建，达到系统模型及控制设计、系统仿真和硬件实现的无缝集成，从而加速控制系统的快速开发.首先，在Matlab/Simulink环境中建立系统控制模型，并利用其自带的定点工具箱对数字控制器进行定点化处理，建立可以移植的带有数字平均滤波的Simulink代码模型.再通过RTDX功能进行算法的调试与验证，并进行代码模型的优化.最终自动生成可靠的C代码到控制器来实现对混合磁悬浮平台的控制，实现在模型仿真和系统实施的集成和统一.并由实物进行了验证．
