Abstract :
In this article, theoretical and experimental study are presented for positive and inverse characteristics of magnetically controlled shape memory alloy (MSMA). The experiment model of self-sensing actuator (SSA) based on MSMA is designed. And working principle of the prototype & a mathematical model are shown. The experiment model of SSA based on MSMA uses dual-coil structure with sensor coil and magnetic coil being in the same magnetic circuit. While it separates signals using space division multiplexing. SSA is applied to experiment of the active vibration control and better results is achieved.
