基于DSP的全数字交流调速系统硬件设计

DSP Based Hardware Design of All-Digital AC Variable Speed Control System

讨论了基于DSP TMS320F240的全数字交流调速系统的硬件设计。从功能和硬件上将交流调速系统分解为DSP控制子系统、驱动子系统、功率子系统和信息处理子系统。详细介绍了各部分的硬件设计。这种结构化的方案有助于实现多种复杂的算法,从而实现高效率和高精度的交流感应电机的驱动控制,同时也方便地实现透明扩展。

We propose a hardware design for an all-digital AC variable speed control system. Including four subsystems, DSP control subsystem, drive subsystem, power subsystem and information co-processing subsystem, the structured system is implemented by TMS320F240, which integrates a high computational DSP power with all necessary motor control peripherals into a single chip. We also present the detailed design for the four subsystems. The proposed system is adequate to implement a highly efficient and accurate AC induction drive control and easily to be extended with a transparent structure.
