英文摘要：

Based on magnetically shape memory alloy （MSMA） with bidirectional reversibility, a principle model is proposed for the MSMA self-sensing actuator of time-sharing control. Feature and performance of the MSMA linear actuator are introduced using two different control strategies. According to the physical parameters changes of MSMA reverse characteristics, schemes for making different type of sensors are presented. The magnetic permeability rate is analysed with effecting on MSMA reverse characteristics; Key technology and solution of the MSMA self-sensing actuator are described.
