Research on double outputs high-precision digital control stabile voltage power for diphase opposition giant magnetostrictive self-sensing actuator
Structure and principle of a new kind of diphase opposition giant magnetostrictive self-sensing actuator (SSA for short) is introduced, for which a kind of double outputs high-precision digital control stable voltage power is designed. With the method of combining with the hardware design and the software setting, the controllability and reliability of the actuator are greatly improved. And the whole design becomes more reasonable, which saves the cost and improves the practicability. The simulation result shows that the voltage power can high-speed and accurately control both output voltages, and that the power amplifier circuit can amplifying output power without distortion in tolerance. In addition, based on the bridge analysis model with variable inductance, dynamic balance separation technology for the SSA with least means square self-adapting (LMS) algorithm is put forward. And based on the micro controller unit (MCU) with high-speed control, the scheme design of the real-time separation circuit for dynamic balance signal can effectively identify out and pick up the induction signal which changes from foreign pressure feed back. Then the SSA real-time, dynamic and accurately controlling is realized.
