基于模糊PID的无刷双馈电机矢量控制

Field Oriented Control Based on Fuzzy-PID Controller for Brushless Double-fed Machine

采用磁场定向矢量控制技术的无刷双馈电机调速系统,其性能基本能够满足运行要求,但存在超调及动态稳定慢等问题。文章将模糊控制和PID控制技术相结合,应用于无刷双馈电机调速系统,并在起动和稳态情况下进行仿真,取得了比单独采用PID控制明显良好的控制效果。

The brushless doubly - fed machine （BDFM） is based on the technic of field oriented control and the performance of its adjustable - speed drive can ultimately meet the need of the operation. But it still remains some problems. For example, steady - state and dynamic performance characteristics aren optimum. Thus ,a new controller is designed to achieve competitive drive performance. In this paper, the implementation of fuzz- y - PID controler in field oriented control system of BDFM for adjustable speed drives is presented,and the results of the simulations show that the response is well behaved.
