A Series Resonant Frequency Identification Method for Ultrasonic Motors Based on Equivalent Circuit Model
在超声波电机运行过程中,由于负载、温升等因素的影响,电机的串联谐振频率会发生漂移.为了对电 机进行精确控制,需要准确识别并跟踪电机的串联谐振频率.基于超声波电机的Butterworth-Van Dyke(BVD)等效电路模型,提出电机的串联谐振频率识别方法.利用电机端电压和端电流作为反馈信号,对反馈信号进行处理得到差分电压,进而得到电机端电压与差分电压的相位差,并分析了该相位差与串联谐振频率的关系.在此基础上,设计了相应的电路实现方案,制作了电路…查看全部>>
