摘    要:提出了一种全数字化的基于电流矢量控制算法的交流电机速度伺服系统控制器的硬件设计方案,并在一片现场可编程门阵列FPGA中得到了具体验证和实现。该方案综合运用了矢量控制算法、M/T测速算法、PI调节算法、SVPWM算法以及EDA设计方法学等,在速度伺服或位置伺服等高性能运动控制系统中有重要的应用价值。所设计的控制器集成电路提供了标准的主机通信接口,可以对各种控制参数进行在线调整,其电流环和速度环的采样频率均可以达到20kHz以上。实验结果表明,该控制器在低速与高速运行状态下均能获得良好的动态和静态性能,其可控转速范围为0.2—10000r/min。

Abstract:This paper presents a fully digitized hardware design scheme of a current-vector-controlled speed servo controller, which is verified and implemented on one-chip field programmable gate arrays (FPGA), for high-performance AC drives. This scheme integrates the vector control strategy, the M/T speed measurement algorithm, the PI regulating technique and the SVPWM principle as well as the EDA design methodology, and it will be a good substitute for traditional motion control practice. The realized controller IC also contains a standard host communication interface, which enables the online configuration for all kinds of control parameters. The actual sample frequencies of the current loop and the speed loop are limited by the selected FPGA; In the Xilinx FPGA prototype mentioned in this paper, the both loops can be set to a frequency of above 20kHz. Experimental results indicate that the controller can provide a controllable speed range from 0.2 to 10000 r/min with satisfactory dynamic and static performances.
Keywords:AC electrical machine  Vector control  Speed servo control  FPGA
