Abstract
To realize the precise control of the micro-vibration of the giant magnetostrictive actuators, a high power program controlled electric driving system, including constant current driving circuit and power supply circuit, is designed. Firstly, the principle and the control structure of the electric driving system used in the circuit are studied. Then, the specific design of the circuit and the selection of components are described in detail. Besides, the topological structure and the specific circuit design of the power supply for the drive circuit are introduced. The experimental result shows that the linearity degree of the input voltage vs. the output current of the high power constant-current driving circuit is 0.105%;the time drift of the output current is 3 mA/h;and the frequency is up to 500 Hz. The 1 Hz and 5 Hz sinusoidal output is realized for the giant magnetostrictive actuator. Thus, the requirements of high precision and stability of the output micro-vibration of the giant magnetostrictive actuators are satisfied.关键词
