摘要
为进一步提高直流电机电子系统在复杂战场环境下的可靠性,在一片FPGA芯片上采用虚拟可重构电路(Virtual Reconfigurable Circuit,VRC)的演化硬件(Evolvable Hardware,EHW)技术设计了电机电路容错控制系统[1],建立了利用MicroBlaze软核配置虚拟可重构电路的演化模型,给出了电机电路容错控制系统的工作流程,探讨了进行电路故障容错的研究与测试;最后在直流无刷电机控制电路中模拟电磁辐射单粒子烧毁逻辑门产生常见的SA错误,使电机不能正常运转,在容错模式下通过在片演化方法,绕过故障单元使电机恢复转动;实验证明使用虚拟可重构的演化方法可以有效地解决电路中的SA故障,使电机控制电路具有容错能力。
In order to further improve the reliability of the DC motor electrical systems in the complex battlefield environment,the authors use Virtual Reconfigurable Circuit（VRC）of Evolvable Hardware（Evolvable Hardware,EHW）technology to design the motor Circuit fault tolerant control system on a FPGA chip and establish the evolution model by using the MicroBlaze soft core to configurate the Virtual Reconfigurable Circuit.Then the work process of motor Circuit fault tolerant control system is given out and the research and test for circuit fault tolerance are discussed.Finally the experiment simulates the common SA-Fault of electromagnetic radiation in the brushless DC motor control circuit,the motor will not operate properly.The evolution method bypass the fault unit to recovery the motor under the mode of fault tolerance.It is proved that using virtual reconfigurable evolution method can effectively solve the SA of circuit failure and make the motor control circuit get the abilities of fault tolerance.
