基于模糊控制的凸极永磁同步电动机最大转矩/电流比控制策略系统仿真

Simulation of Salient Pole Permanent Magnet Synchronous Machine Based on Fuzzy Control and Maximum Torque/Ampere

永磁同步电机以其自身特殊的结构,较其他类型的电动机具有很多方面的优势,如:功率密度高,转子惯性低等,永磁同步电机可分为凸极和隐极式电机,结构不同其控制方法又有不同。本文针对凸极式永磁同步电机的特点,分析了最大转矩/电流比控制策略,并在调速系统中应用了模糊控制和PI控制相结合的转速调节器,仿真结果表明,这种控制方法较传统的id=0的PI控制策略的有较大的改进。

The permanent magnet synchronous machine（PMSM） has a special structure, the advantages are higher power density, lower rotor inertia. There are two kinds of PMSM,they are salient pole motor and non-salient pole motor ,they have different controls .This paper analyze the current vector control with maximum torque/ampere, and apply fuzzy-PI control in a speed control system. The result shows that there is an improvement compared with the traditional control with id=0 and PI control.
