摘要:
将Markov链引入到传统随机脉宽调制(PWM)技术中,提出了一种基于Markov链的变频调速系统随机PWM技术。能够使随机周期值更均匀地分布在期望周期的周围,从而使输出电流频谱分布更加均匀、减小电机的电磁噪声和机械振动,而且与传统随机PWM相比,输出电流的纹波有明显的减小,提高了系统的控制性能。仿真和实验结果验证了算法的有效性。
Abstract:
The Markov chain is introduced into the conventional random PWM in this paper,and a novel random PWM technology of frequency control system based on Markov chain is proposed.The random cycle values can be evenly distributed around the cycle expectations,and thus the output current spectrum was also distributed evenly and the electromagnetic noise and machanical vibration of the induction motor were reduced.Compared to the conventional random PWM,the output current ripples were reduced,and the control perfor...
