摘　　要：为了提高混合励磁同步电机id?0矢量控制调速系统的动态性能,采用基于双幂次趋近率的滑模控制方法设计了速度控制器。该方法不仅避免了常规幂次趋近率的系统超调与趋近速度之间的矛盾,还增强了混合励磁同步电机调速系统的抗扰动能力。最后,进行了仿真对比,结果表明,基于双幂次趋近率的滑模控制设计的速度控制器能够有效地提高调速系统的动态性能。In order to improve the dynamic quality of hybrid excitation synchronous motor in the i_d =0 field-oriented control system, a speed controller based on double power reaching rate sliding mode control is adopted. The reaching law not only avoids the contradiction between the overshooting of the system based on conventional power reaching rate and the approaching speed,but also strengthens disturbance rejection ability of the hybrid excitation synchronous motor speed control system. Finally, the simulation results show that the speed controller based on double power reaching rate sliding mode control can effectively improve the dynamic performance of the speed control system.
