摘要
针对矩阵变换器双电压合成控制策略和永磁同步电机磁场定向控制的特点,以网侧输入性能和电机调速性能为控制目标,给出了永磁同步电机的交-交直接控制。分析双电压合成控制策略的原理并构建了基于dSPACE为主控单元的矩阵变换器—永磁同步电机调速系统的实验系统。仿真及试验结果表明,采用双电压合成控制策略的矩阵变换器—永磁同步电机调速系统达到了良好的控制效果,实现了较好的网侧输入性能。
Aiming at the performance of power factor and the speed regulating, the direct AC- AC control of permanent magnet synchronous motor（PMSM） with the consideration of the characteristics of matrix converter＇s two line voltage synthesis and flux-oriented control was introduced. The principle of two line voltage synthesis was presented particularly and the MC--PMSM speed regulating system was constructed based on dSPACE, and the platform of speed regulating system was set up. Simulations and experiment results indicate that the system deserves good speed regulating and source side effect with two line voltage synthesis.
