摘要：
The self-sensing actuator can realize the each other conversion between mechanical force and electromagnetic signal, which is developed based on reversible characteristic of magnetically controlled shape memory alloy (MSMA), the two-way transduction characteristics were implemented by using the MSMA element as the key component. The equivalent magnetic circuit method and finite element analysis were combined to analyze and design the core structure of the self-sensing actuator, the total magnetic resistance of the magnetic circuit and the excitation power of the device were reduced effectively. For the interference component in the sensing signal, signal processing using an adaptive filter in accordance with the least mean square algorithm (LMS), the filter can automatically update the filter coefficient according to the change of signal frequency, and the signal noise of different band is effectively filtered out. Combining the method of time-division control, the switch circuit was designed in the process of sensing and executing of the self-sensing actuator, and executed timing control the self-sensing actuator, the decoupling is accomplished between sensing signal and control signal. © 2021, Harbin University of Science and Technology Publication.
