In the actuator control, has used the MOOG valve servo-control mechanism, avoided the disadvantage factor which the control system wide range adjustment roller is apart from brings.

This paper discusses the principle of nanometer electromagnetic impulsive actuators, gives some typical structures, and presents a combination actuator of new mechanism developed by the authors.

Using the mechanism of the piezoelectric effect of piezoelectric materials to design a piezoelectric actuator bar master, and analyze its working principle and design method.
