摘　　要：针对电机控制系统对高精度、小功耗和低成本的需求,设计空间电压矢量脉宽调制(SVPWM)的U/F调速控制系统。设计中选用TI的高速数字信号处理器TMS320F28335作为控制核心,描绘出系统总体设计框图,详细阐述完整的SVPWM实现过程,给出系统各个模块的硬件设计思路和系统控制程序设计思路。通过实验验证系统设计的可行性、合理性。Aiming at the demand of the motor control system for high precision, low power consumption and low cost, designs the U/F speed control system of space vector pulse width modulation（SVPWM）. TI＇s high-speed digital signal processor（tms320 f28335） is selected as the core of the control in the design. Describes the overall design diagram of the system, and expounds the complete SVPWM control process in detail,presents the hardware design idea and the system control program design idea of each module of the system. The feasibility and rationality of the system design are verified by experiments.
