摘要
基于对伪微分反馈控制理论的研究和应用,结合永磁同步电机(PMSM)特点,设计出了PMSM调速系统中的基于PDF控制的电流环及基于PDF控制的速度环控制器。通过模型推导、系统仿真性能比较,验证了PDF策略在永磁同步电机速度控制中的可用性和优越性能,特别表现在系统动态响应特性和控制精度方面。
In the paper,the control theory and design method of PDF were introduced.Combined with the characteristic of PMSM,it designed a current loop and a speed loop controller based on PDF control in the speed regulating system of PMSM.By means of model deducing and comparison in performance of system simulation,it verified the usability and excellent performance of PDF strategy in the speed control of PMSM,and it especially represented in two aspects of control precision and characteristic of system dynamic response.
