| 摘要: |
| 根据磁浮开关磁阻电机(SRM)对控制器硬件资源及实时性的要求,基于双DSP与双口RAM,研制了磁浮SRM的全数字控制器。控制器以2片DSP为核心,来满足磁浮SRM旋转和悬浮功率变换器对PWM调制信号的需求,双口RAM用于实现2个DSP之间的信息实时共享,旋转控制用功率变换器采用传统不对称半桥电路,悬浮用功率变换器采用2块IPM模块,双DSP管理3套功率变换器以实现同时旋转控制和悬浮控制。制作了全数字控制器实验样机,进行了实验测试。实验结果表明,两DSP可协调工作,实时交换所需数据,能有效地完成对磁浮SRM的控制。 |

| Abstract: |
| To meet the requirements of magnetic suspending SRM(Switched Reluctance Motor) for the hardware resource and real-time performance of controller,a digital controller is designed based on two DSPs and dual-port RAM.DSPs provide PWM signals to power inverters,and the dual-port RAM is used to realize real-time data sharing between two DSPs.One power inverter for rotation control applies non-symmetrical semi-bridge structure,and two power inverters for suspension control adopt two IPMs.Three power inverters are all controlled by two DSPs.The prototype is made and tested,and the experimental results verify the cooperative work and real-time data exchange of two DSPs for effective control of magnetic suspending SRM. |
