| 摘 要： | 波波夫谐波线性化可较为准确地分析与研究复杂高阶非线性系统自持振荡的稳定性问题．将其运用到电动摩托车双闭环无刷直流电机的自持振荡研究当中，并采用Matlab计算与仿真,研究结果表明，双闭环中速度环可产生不稳定的自持振荡，电流环不会产生自持振荡，但有可能引起系统的不稳定，与实测结果相符合,说明速度环与电流环拥有不同的调节特点，两者相结合可以保证电动摩托车稳定运行；同时，波波夫谐波线性化对无刷直流电机的非线性稳定性研究很有帮助。

| Abstract: | Е.П.Попов harmonic linearization is known as an efficient method to analyze the stabilization of self-oscillations of non-linear high-dimension systems.This paper introduces the method to solve self-oscillation of brushless DC motor used by electric bicycle.The applications of the method are obtained through the programming and simulation of MATLAB.The results show that although the speed loop can cause unstable self-oscillations and the current loop can cause unstable system problems,the combination of the two loops can still ensure the stable performance of motor concerning their different operations.Е.П.Попов harmonic linearization is also proved to be helpful to solve problems about self-oscillation caused by brushless DC motors. |
