摘要
无刷直流电机(BLDCM)是一种多变量和非线性的控制系统,参考模型和模糊控制结合起来在其控制中得到应用。针对参考模型结构固定和模糊控制不适用参数在线调整方面的不足,文中提出了一种参考模型模糊控制的方法,并用于无刷直流电机的控制中。该方法在Matlab/Simulik中按功能模块化建模仿真,用M文件编写功能函数,实现BLDCM控制。仿真结果表明,采用模糊控制对BLDCM系统进行实时控制,系统稳定性改善,响应速度加快,系统的综合性能得到提高。该模型具有很强的自适应能力,可以方便地进行功能模块的修改,为今后分析该类电机和对其控制策略的研究提出了新的方法,在BLDCM研究方面具有很强的借鉴意义。
Brushless DC motor(BLDCM)is a multivariable and nonlinear control system.The reference model and fuzzy control are combined to be used in its control.Aiming at the shortcomings of reference model structure fixed and fuzzy control unsuitable application parameters online adjustment,a reference model fuzzy control method is proposed in this paper and used in the control of brushless DC motor.The method is modularized and simulated according to function in Matlab/Simulik,and the function is written by M file to realize BLDCM control.The simulation results show that the fuzzy control is used to control the BLDCM system in real time.The stability of the system is improved,the response speed is accelerated,and the comprehensive performance of the system is improved.The model has strong adaptive ability and can be easily modified to function modules.The analysis of this type of motor and its research on control strategy proposes a new method,which has a strong reference significance in BLDCM research.
