摘要
介绍了永磁同步电动机(PMSM)的矢量控制,采用电流、速度双闭环控制,以TMS320F2812为核心,同时将空间矢量脉宽调制(SVPWM)技术应用到系统中。阐述了整个控制系统的工作原理、硬件结构及软件编程,最后对整个控制系统在不同测试条件下进行试验分析,试验结果证明了该控制模型的有效性及其抗干扰性强、转速超调小、动态响应速度快等优点。
A vector control system of permanent magnet synchronous motor（PMSM） was introduced.A double closed-loop control system with current and speed loop was applied with TMS320F2812 as core of the system.The space vector pulse width modulation（SVPWM） was used in the control system.It stated the control system principle and introduced the hardware and the software program of the system.Finally,the whole control system was simulated under different test conditions.The simulation results proved that the system had many advantages such as the effec-tiveness of the control model,small speed overshoot,excellent antrinterference technique and rapid dynamic response and so on.
