模糊控制的无刷直流电机调速系统

Speed Control System With Fuzzy Control for Brushless DC Motor

无刷直流电机具有结构简单、运行可靠、维护方便以及调速性能好的优点。针对传统的PID控制不能获得理想的控制性能，对外界的干扰的适应性较弱，鲁棒性较差的缺点，提出了一种基于模糊控制的智能控制策略，通过与传统PID仿真对比发现，结果表明模糊控制对负载扰动具有较强的抗干扰性，系统的动态性能和稳态性能均有提高。

Brushless DC motor has some advantages such as simple structure, reliable operation, easy maintenance and good speed performance. An ideal control performance cannot be obtained for traditional PID control which is not adaptability for outside interference and poor robustness. An intelligent control strategy based on fuzzy control is proposed in this paper. Compared with traditional PID, the simulation results shows that fuzzy control has a better anti-interference for load disturbance and the dynamic performance and steady-state performance of the system are improved.
