摘　　要：针对无刷直流电机的高性能控制要求,提出了一种基于嵌入式操作系统的无刷直流电动机模糊控制系统设计方法.系统采用嵌入式操作系统μC/OS-Ⅱ作为系统管理软件,并将模糊控制和PID控制通过自适应因子结合,在线自调整控制参数,最后在基于DSP的控制器中运用该编程方法实现了上述控制思想.实验表明,将嵌入式操作系统应用于无刷直流电机控制器切实可行,且实时性强,性能可靠,同时验证了模糊PID调速系统设计与编程方法的可行性,提高了系统的控制精度且系统具有良好的动态性能,系统设计合理,具有很高的实用和参考价值.Due to the requiement of high control performances for brushless DC motor （BLDCM）, fuzzy control system design of BLDCM based on embedded operating system was proposed. Using the embedded operating system μC/OS-Ⅱ as the administrate software of the system and combining fuzzy-adaptive control with PID by the adaptive factor, the control parameters were adjusted on-line. At last, the control method was implemented in DSP based on the proposed approach. The simulation and experimental results show that applying embedded operation system to controller of BLDCM is feasible, and the model and programming method are valid, The desgned system and can be used in other fields. possesses very good static and dynamic performances .
