摘  要：由于BLDCM在运行中受环境变化、元件老化等问题影响，传统的PI控制难以取得满意的效果。该文通过免疫系统与控制系统的类比，借鉴免疫响应调节机理，提出了将模糊免疫PI控制器应用BLDCM控制系统中。Matlab仿真结果表明，系统超调量小，速度响应快，对外界干扰得到了很好的抑制，具有较好的控制精度和较好的鲁棒性，控制系统性能优于常规PI控制。

Abstract: The BLDCM is often effected by environmental changes and ageing of electronic components in operation，the traditional PI control is difficult to obtain satisfactory results.Based on the immune system regulating law and the comparison of the sensorless BLDCM control system and the immune system, a fuzzy immune PI controller was proposed to use in BLDCM control system in this paper.The simulation results illustrate that excellent flexibility and adaptability and high precision as well as good robustness are obtained by the proposed strategy,so the fuzzy immune PI control method is superior to the traditional PI control method.
