摘　　要：为了设计高精度的直流无刷电机伺服控制系统,性能优良的位置跟踪控制器是其重要保障。基于直流无刷电机的工作原理,运用Matlab模糊工具箱建立其自动位置跟踪控制系统的计算机仿真模型,系统的电流和速度环采用PI控制,结合PID控制和模糊控制设计了系统位置环的模糊PID控制器。数字仿真结果表明,模糊PID控制的动静态特性优于传统单一的PID控制,对设计性能优良的直流无刷电机控制器具有借鉴意义。The position tracking controller with good performance is the guarantee of high precision brushless DC motor servo system. A mathematic model based on fuzzy logic toolbox for position tracking control system was established based on the working principle of brushless DC Motor. The PI controller designed was for current and speed loop and Fuzzy PID controller designed was the collaboration of PID control and fuzzy control for system position loop. The result of simulation shows that, compared with the PID controller, the dynamic performance of fuzzy controller is better. The research work of this paper is of significance to excellent controller design.
