摘　　要：该文针对电磁开关在PWM闭环控制下引起的高频吸持噪声问题展开研究,提出一种电磁开关高频吸持噪声抑制的自适应控制策略。首先,分析电磁开关PWM闭环控制高频吸持噪声产生的几个影响因素,据此提出需要综合采取三项措施来抑制这一高频噪声;然后,结合电磁开关实际运行特点,设计基于模糊控制的电磁开关高频吸持噪声自适应抑制策略,通过模糊控制逻辑整合on/off控制、自整定PID控制以及伪开环控制各自的优点,来实施噪声抑制措施;最后,构建电磁开关联合仿真模型,开发基于CompactRIO的电磁开关快速控制原型验证系统,对电磁开关噪声与振动信号进行频域分析,对控制策略进行验证,仿真及实验结果证明所提控制策略能够有效抑制电磁开关的高频吸持噪声。The problem of high-frequency holding noise caused by electromagnetic switch under PWM closed-loop control is studied,and an adaptive control strategy for electromagnetic switch high-frequency holding noise is proposed in this paper.Firstly,the mechanism of electromagnetic switch high-frequency closed-loop noise is analyzed,and three measures are proposed to suppress the high-frequency noise.Secondly,according to the actual operation characteristics of electromagnetic switch,an adaptive suppression strategy of electromagnetic switch high-frequency holding noise based on fuzzy control is designed.By integrating the advantages of on/off control,self-tuning PID control and pseudo open-loop control,the noise suppression measures are implemented.Finally,the electromagnetic switch co-simulation model is constructed,and the rapid control prototype verification system of electromagnetic switch based on CompactRIO is developed.The frequency domain analysis of electromagnetic switch noise and vibration signal is carried out,and the control strategy is verified.Simulation and experimental results show that the proposed control strategy can effectively suppress the high-frequency holding noise of electromagnetic switch.
