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．

Hybrid magnetic suspension platform control design and implementation based on model design methodology

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．
