摘要
阐述了磁悬浮无轴承电机悬浮原理,分析了转子上所受的作用力,根据径向单边磁拉力所起作用为正反馈所导致的系统被控对象不稳定这一特点,设计了相应的PID调节器;利用MATLAB/Simulink对系统动态过程进行了仿真后,基于TMS320LF2407采用增量式PID算法设计了DSP程序,程序运行后经比较与用MATLAB编写的验证程序结果完全一致;设计出的系统在响应速度、调整时间和稳定性方面完全满足要求,达到了良好的效果,具有较强的实际意义。
The magnetic suspension bearingless motor principle is described, and the levitation force on rotor is analyzed. According to the unilateral magnetic pull of positive feedback as a result of suspension control system instability, the PID controller is designed. After the simulation for the dynamic process using MATLAB/Simulink, the increment PID control algorithm programs have been carried out based on TMS320LF2407, the result of DSP programs after running compared with the verification process prepared by MATLAB are fully consistent, which show that the system response time, stability and precision fully meet the requirements and achieved good results. And it would have a strong practical significance.
