摘要
电流环是构成高性能永磁同步电机伺服系统的根本,其动态响应特性直接关系到矢量控制策略的实现。针对实际控制系统中所采用的传统PI电流调节器忽略交直轴电流的耦合的问题,设计了以反馈电流和反馈速度为输入的电压前馈补偿的电流调节器。通过在矢量控制系统的仿真表明,采用电压前馈型电流调节器的系统相对于传统的PI电流调节器的系统,具有更好的动态特性、更快的响应速度。最后在基于TMS320F28335的永磁同步电机矢量控制系统上进行实验验证,实验结果进一步验证了仿真结果。
Current loop is the basis of a high performance permanent magnet synchronous motor servo system, the dynamic response is directly related to the realization of the vector control strategy. In view of the actual control system adopted by the traditional PI current regulator ignore d axis and q axis current coupling problem, designed the velocity feedback and current feedback as the input voltage feed-forward compensation current regulator. In vector control system simulation show that the voltage feed forward current regulator system compared with traditional PI current regulator system, has better dynamic characteristics, faster response speed. Finally in the permanent magnet synchronous motor vector control system based on TMS320F28335 on experiment, the experimental results further verified the simulation results.
