摘　　要：针对无刷直流电机参数的改变会使系统的稳定性发生变化的问题,研究了无刷直流电机(BLDCM)在不同参数条件下的混沌特性。基于BLDCM负载、空载运行状态的数学模型分析其混沌特性,采用状态延时反馈方法对BLDCM实现混沌反控制;基于Lyapunov稳定性原理,设计了lorenz-like的系统反推同步控制器,并进行了稳定性研究。利用Multisim设计了基于电流转换器(CCCⅡ)的仿真电路,通过Matlab数值仿真及电路实现,验证了该方法的准确性和有效性。In view of the changes in the parameters of the brushless DC motor,the stability of the system will be changed.The chaotic characteristics of BLDCM under different parameters are studied.The chaotic characteristics of BLDCM are analyzed based on mathematical models of BLDCM load and no⁃load operating states.Based on the state⁃delayed feedback method,anti⁃chaos control of BLDCM was implemented.Based on the Lyapunov stability principle,a lorenz⁃like system was designed to reverse the synchronization controller and the stability study was conducted.Multisim was used to design the current conversion(CCCⅡ)simulation circuit,through Matlab numerical simulation and circuit implementation,verified the accuracy and effectiveness of the method.
