Control Logic Design for Bearingless Switched Reluctance Motor based on CPLD

介绍了无轴承开关磁阻电机(Bearingless Switched Reluctance Motors,简称BSRM)的悬浮原理、系统构成和功率电路拓扑结构,并根据其控制系统的复杂逻辑特点,详细介绍了对复杂可编程逻辑器件(Complex Programmable Logic Device,简称CPLD)逻辑功能的要求,给出了设计原则。在此基础上,设计了基于MAXⅡEPM1270芯片的逻辑控制系统。在QuartusⅡ环境下对设计程序进行了仿真分析,并在硬件电路上进行了主绕组、悬浮绕组信号实验,验证了控制逻辑设计的正确性和可靠性。

Bearingless Switched Reluctance Motors （BSRM）are high speed electric machines combined with radial magnetic bearing functions.In this paper,the principle of radial force generation,control system construction and power circuits are introduced briefly.In view of the complex control strategy of BSRM system,the requirements of logical function and design principal for the BSRM system are introduced in detail.Based on above,the control logic block based on MAX Ⅱ is designed.The simulation and experimentation for main ＆ radial force winding signals validate the reliability and cor-rectness of the proposed logic controller.
