在各个领域，需要小型驱动系统来帮助人类在狭窄的空间中进行活动，实现精细运动。虽然已经开发了一些微型执行器，但连接到它们的传感器的大小阻碍了系统的小型化。本文提出了一种采用紧凑型螺线管作动器的无位置传感器驱动系统。使用包括AC和DC分量的输入信号。根据交流分量估计电感和位置。采用直流元件驱动螺线管执行器。在频率特性和同时估计方面进行了仿真和实验，验证了该方案的有效性。从频率特性的结果可以准确地估计出高达10赫兹频率的位置和力。作为同时估计的结果，实时地同时估计位置和力。这一方案是有用的，因为实现了一种小型电磁铁驱动系统，其位置和力同时被实时估计，而不需要任何位置和力传感器。
In various fields, small actuation systems are required to aid human activities in a narrow space and to realize fine motions. Although some miniature actuators have been developed, the size of the sensors attached to them prevents the miniaturization of the systems. In this paper, a sensorless actuation system with a compact solenoid actuator is proposed. An input signal including the AC and DC components is used. The inductance and position are estimated from the AC component. The DC component is applied in order to drive the solenoid actuator. Simulations and experiments concerning frequency characteristics and simultaneous estimation are conducted to verify the validity of the proposal. From the results of the frequency characteristics, the position and force estimation are accurately achieved up to 10 Hz frequency. As a result of the simultaneous estimation, the position and force are simultaneously estimated in real time. This proposal is useful, because a small solenoid actuation system whose position and force are simultaneously estimated in real time without the need for any position and force sensors is realized.
