摘　　要：根据永磁同步电机的数学模型和坐标变换的原理,介绍了矢量调速系统,利用数学方程推导了电流环和速度环PI控制器的传递函数和参数解析计算式。基于TMS320F2812平台,结合实际系统,考虑误差和参数补偿,完成双闭环调速系统的设计。实验结果表明,该永磁同步电机双闭环矢量调速系统能够稳定运行,并有良好的控制性能,快速、准确完成闭环调速功能。According to the mathematical model of permanent magnet synchronous motor and the principle of coordinate transformation,the vector speed control system is introduced.And the transfer function and parameter resolution equations of current loop and speed loop PI controller are derived using mathematical equations.Based on the TMS320F2812 platform,the design of the dual closed-loop speed regulation system is completed by combining the actual system and considering the error and parameter compensation.The experimental results show that the dual closed-loop vector speed regulation system of the permanent magnet synchronous motor can operate stably and has good control performance to complete the closed-loop speed regulation function quickly and accurately.
