摘要
为了研究与实现高性能、全数字化的速度伺服系统,在永磁同步电动机的数学模型基础上,依据矢量控制理论,采用现代EDA设计方法,利用可编程逻辑阵列(FPGA)、智能功率模块(IPM)和增量式光电编码器等,实现了基于转子磁场定向控制(FOC)策略的全数字化速度伺服系统,给出了位置检测、调节器、矢量变换、电压空间矢量脉宽调制(SVPWM)和通讯等模块的实现方法。实验结果表明,该系统能够在8μs内完成矢量控制算法,其电流环带宽达到4kHz,具有响应快速,调速范围宽等优点。
To study and implement high-performance and digital speed servo system, on the basis of the mathematical model of permanent magnetic synchronous motor and the theory of vector control, a digital Field-Oriented-controlled speed servo system realized on theplatform of one-chip FPGA, IPM and Incremental encoder has been proposed adopting modem EDA design technology. The implementation of functional modules, such as position measurement, regulator, vector transformation, SVPWM and communication is proposed. The experimental result is given at last. This system completes the vector control algorithm in 8μs, the bandwidth of current loop is 4 kHz, so this system has the advantage of fast response, wide speed range and so on.
